Given numbers are 620,979,458,352,710
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,979,458,352,710 is 78951102560.
Find LCM of 620,979,458,352,710 with Prime Factorization
| 2 | 620, 979, 458, 352, 710 |
| 2 | 310, 979, 229, 176, 355 |
| 5 | 155, 979, 229, 88, 355 |
| 11 | 31, 979, 229, 88, 71 |
| 31, 89, 229, 8, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 31 x 89 x 229 x 8 x 71 = 78951102560
Therefore, the lowest common multiple of 620,979,458,352,710 is 78951102560.
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.
620 x 979 x 458 x 352 x 710 = 69476970252800
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
979 : 1, 11, 89, 979
458 : 1, 2, 229, 458
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
710 : 1, 2, 5, 10, 71, 142, 355, 710
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,979,458,352,710, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
979:11x 89
458:2x 229
352:2x 2x 2x 2x 2x 11
710:2x 5x 71
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 5x 11 = 880
Therefore, the value for common factors is 880.
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 = 69476970252800/(1x880)
LCM = 69476970252800/880
LCM = 78951102560
Thus, we can understand that the LCM of 620,979,458,352,710 is 78951102560.
