Find LCM of 688,157,944,535,581 with Prime Factorization
| 2 | 688, 157, 944, 535, 581 |
| 2 | 344, 157, 472, 535, 581 |
| 2 | 172, 157, 236, 535, 581 |
| 2 | 86, 157, 118, 535, 581 |
| 43, 157, 59, 535, 581 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 43 x 157 x 59 x 535 x 581 = 1980934048240
Therefore, the lowest common multiple of 688,157,944,535,581 is 1980934048240.
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.
688 x 157 x 944 x 535 x 581 = 31694944771840
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
157 : 1, 157
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
535 : 1, 5, 107, 535
581 : 1, 7, 83, 581
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,157,944,535,581, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
157:157
944:2x 2x 2x 2x 59
535:5x 107
581:7x 83
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 2 = 16
Therefore, the value for common factors is 16.
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 = 31694944771840/(1x16)
LCM = 31694944771840/16
LCM = 1980934048240
Thus, we can understand that the LCM of 688,157,944,535,581 is 1980934048240.
