Given numbers are 657,814,328,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,814,328,902 is 87706872.
Find LCM of 657,814,328,902 with Prime Factorization
| 2 | 657, 814, 328, 902 |
| 11 | 657, 407, 164, 451 |
| 41 | 657, 37, 164, 41 |
| 657, 37, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 41 x 657 x 37 x 4 x 1 = 87706872
Therefore, the lowest common multiple of 657,814,328,902 is 87706872.
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.
657 x 814 x 328 x 902 = 158223197088
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.
657 : 1, 3, 9, 73, 219, 657
814 : 1, 2, 11, 22, 37, 74, 407, 814
328 : 1, 2, 4, 8, 41, 82, 164, 328
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,814,328,902, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
814:2x 11x 37
328:2x 2x 2x 41
902:2x 11x 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 11x 41 = 1804
Therefore, the value for common factors is 1804.
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 = 158223197088/(1x1804)
LCM = 158223197088/1804
LCM = 87706872
Thus, we can understand that the LCM of 657,814,328,902 is 87706872.
