Given numbers are 634,447,102,748,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,447,102,748,861 is 30419374524.
Find LCM of 634,447,102,748,861 with Prime Factorization
| 2 | 634, 447, 102, 748, 861 |
| 3 | 317, 447, 51, 374, 861 |
| 17 | 317, 149, 17, 374, 287 |
| 317, 149, 1, 22, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 317 x 149 x 1 x 22 x 287 = 30419374524
Therefore, the lowest common multiple of 634,447,102,748,861 is 30419374524.
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.
634 x 447 x 102 x 748 x 861 = 18616657208688
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.
634 : 1, 2, 317, 634
447 : 1, 3, 149, 447
102 : 1, 2, 3, 6, 17, 34, 51, 102
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,447,102,748,861, is 1.
Now, the common factors can be found like this.
634:2x 317
447:3x 149
102:2x 3x 17
748:2x 2x 11x 17
861:3x 7x 41
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 3x 3x 17 = 612
Therefore, the value for common factors is 612.
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 = 18616657208688/(1x612)
LCM = 18616657208688/612
LCM = 30419374524
Thus, we can understand that the LCM of 634,447,102,748,861 is 30419374524.
