Given numbers are 303,658,620,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 303,658,620,840 is 123611880.
Find LCM of 303,658,620,840 with Prime Factorization
| 2 | 303, 658, 620, 840 |
| 2 | 303, 329, 310, 420 |
| 3 | 303, 329, 155, 210 |
| 5 | 101, 329, 155, 70 |
| 7 | 101, 329, 31, 14 |
| 101, 47, 31, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 101 x 47 x 31 x 2 = 123611880
Therefore, the lowest common multiple of 303,658,620,840 is 123611880.
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.
303 x 658 x 620 x 840 = 103833979200
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.
303 : 1, 3, 101, 303
658 : 1, 2, 7, 14, 47, 94, 329, 658
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 303,658,620,840, is 1.
Now, the common factors can be found like this.
303:3x 101
658:2x 7x 47
620:2x 2x 5x 31
840:2x 2x 2x 3x 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 3x 5x 7 = 840
Therefore, the value for common factors is 840.
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 = 103833979200/(1x840)
LCM = 103833979200/840
LCM = 123611880
Thus, we can understand that the LCM of 303,658,620,840 is 123611880.
