The LCM of 661,944,118,748,701 is 81796190608.
Find LCM of 661,944,118,748,701 with Prime Factorization
| 2 | 661, 944, 118, 748, 701 |
| 2 | 661, 472, 59, 374, 701 |
| 59 | 661, 236, 59, 187, 701 |
| 661, 4, 1, 187, 701 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 59 x 661 x 4 x 1 x 187 x 701 = 81796190608
Therefore, the lowest common multiple of 661,944,118,748,701 is 81796190608.
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.
661 x 944 x 118 x 748 x 701 = 38607801966976
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.
661 : 1, 661
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
118 : 1, 2, 59, 118
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
701 : 1, 701
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,944,118,748,701, is 1.
Now, the common factors can be found like this.
661:661
944:2x 2x 2x 2x 59
118:2x 59
748:2x 2x 11x 17
701:701
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 59 = 472
Therefore, the value for common factors is 472.
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 = 38607801966976/(1x472)
LCM = 38607801966976/472
LCM = 81796190608
Thus, we can understand that the LCM of 661,944,118,748,701 is 81796190608.
