Given numbers are 637,781,875,175
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,781,875,175 is 62187125.
Find LCM of 637,781,875,175 with Prime Factorization
| 5 | 637, 781, 875, 175 |
| 5 | 637, 781, 175, 35 |
| 7 | 637, 781, 7, 35 |
| 91, 781, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 7 x 91 x 781 x 1 x 5 = 62187125
Therefore, the lowest common multiple of 637,781,875,175 is 62187125.
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.
637 x 781 x 875 x 175 = 76179228125
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.
637 : 1, 7, 13, 49, 91, 637
781 : 1, 11, 71, 781
875 : 1, 5, 7, 25, 35, 125, 175, 875
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,781,875,175, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
781:11x 71
875:5x 5x 5x 7
175:5x 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.
5x 5x 7x 7 = 1225
Therefore, the value for common factors is 1225.
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 = 76179228125/(1x1225)
LCM = 76179228125/1225
LCM = 62187125
Thus, we can understand that the LCM of 637,781,875,175 is 62187125.
