Given numbers are 560,620,755,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 560,620,755,442 is 579320560.
Find LCM of 560,620,755,442 with Prime Factorization
| 2 | 560, 620, 755, 442 |
| 2 | 280, 310, 755, 221 |
| 5 | 140, 155, 755, 221 |
| 28, 31, 151, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 28 x 31 x 151 x 221 = 579320560
Therefore, the lowest common multiple of 560,620,755,442 is 579320560.
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.
560 x 620 x 755 x 442 = 115864112000
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.
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
755 : 1, 5, 151, 755
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 560,620,755,442, is 1.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
620:2x 2x 5x 31
755:5x 151
442:2x 13x 17
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 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 115864112000/(1x200)
LCM = 115864112000/200
LCM = 579320560
Thus, we can understand that the LCM of 560,620,755,442 is 579320560.
