The LCM of 721,974,824,236,154 is 1823051384.
Find LCM of 721,974,824,236,154 with Prime Factorization
| 2 | 721, 974, 824, 236, 154 |
| 2 | 721, 487, 412, 118, 77 |
| 7 | 721, 487, 206, 59, 77 |
| 103 | 103, 487, 206, 59, 11 |
| 1, 487, 2, 59, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 103 x 1 x 487 x 2 x 59 x 11 = 1823051384
Therefore, the lowest common multiple of 721,974,824,236,154 is 1823051384.
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.
721 x 974 x 824 x 236 x 154 = 21030720765824
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.
721 : 1, 7, 103, 721
974 : 1, 2, 487, 974
824 : 1, 2, 4, 8, 103, 206, 412, 824
236 : 1, 2, 4, 59, 118, 236
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,974,824,236,154, is 1.
Now, the common factors can be found like this.
721:7x 103
974:2x 487
824:2x 2x 2x 103
236:2x 2x 59
154:2x 7x 11
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 7x 103 = 11536
Therefore, the value for common factors is 11536.
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 = 21030720765824/(1x11536)
LCM = 21030720765824/11536
LCM = 1823051384
Thus, we can understand that the LCM of 721,974,824,236,154 is 1823051384.
