Find LCM of 180,646,407,156,748 with Prime Factorization
| 2 | 180, 646, 407, 156, 748 |
| 2 | 90, 323, 407, 78, 374 |
| 3 | 45, 323, 407, 39, 187 |
| 11 | 15, 323, 407, 13, 187 |
| 17 | 15, 323, 37, 13, 17 |
| 15, 19, 37, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 17 x 15 x 19 x 37 x 13 x 1 = 307618740
Therefore, the lowest common multiple of 180,646,407,156,748 is 307618740.
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.
180 x 646 x 407 x 156 x 748 = 5522371620480
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
646 : 1, 2, 17, 19, 34, 38, 323, 646
407 : 1, 11, 37, 407
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,646,407,156,748, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
646:2x 17x 19
407:11x 37
156:2x 2x 3x 13
748:2x 2x 11x 17
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 2x 2x 3x 11x 17 = 17952
Therefore, the value for common factors is 17952.
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 = 5522371620480/(1x17952)
LCM = 5522371620480/17952
LCM = 307618740
Thus, we can understand that the LCM of 180,646,407,156,748 is 307618740.
