Given numbers are 636,761,758,456,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 636,761,758,456,781 is 5443968616152.
Find LCM of 636,761,758,456,781 with Prime Factorization
| 2 | 636, 761, 758, 456, 781 |
| 2 | 318, 761, 379, 228, 781 |
| 3 | 159, 761, 379, 114, 781 |
| 53, 761, 379, 38, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 53 x 761 x 379 x 38 x 781 = 5443968616152
Therefore, the lowest common multiple of 636,761,758,456,781 is 5443968616152.
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.
636 x 761 x 758 x 456 x 781 = 130655246787648
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
761 : 1, 761
758 : 1, 2, 379, 758
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,761,758,456,781, is 1.
Now, the common factors can be found like this.
636:2x 2x 3x 53
761:761
758:2x 379
456:2x 2x 2x 3x 19
781:11x 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 3 = 24
Therefore, the value for common factors is 24.
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 = 130655246787648/(1x24)
LCM = 130655246787648/24
LCM = 5443968616152
Thus, we can understand that the LCM of 636,761,758,456,781 is 5443968616152.
