Given numbers are 302,780,420,445,560
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 302,780,420,445,560 is 293507760.
Find LCM of 302,780,420,445,560 with Prime Factorization
| 2 | 302, 780, 420, 445, 560 |
| 2 | 151, 390, 210, 445, 280 |
| 3 | 151, 195, 105, 445, 140 |
| 5 | 151, 65, 35, 445, 140 |
| 7 | 151, 13, 7, 89, 28 |
| 151, 13, 1, 89, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 151 x 13 x 1 x 89 x 4 = 293507760
Therefore, the lowest common multiple of 302,780,420,445,560 is 293507760.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
302 x 780 x 420 x 445 x 560 = 24654651840000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
302 : 1, 2, 151, 302
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
445 : 1, 5, 89, 445
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 302,780,420,445,560, is 1.
Now, the common factors can be found like this.
302:2x 151
780:2x 2x 3x 5x 13
420:2x 2x 3x 5x 7
445:5x 89
560:2x 2x 2x 2x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 3x 5x 5x 5x 7 = 84000
Therefore, the value for common factors is 84000.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 24654651840000/(1x84000)
LCM = 24654651840000/84000
LCM = 293507760
Thus, we can understand that the LCM of 302,780,420,445,560 is 293507760.
