Find LCM of 974,944,714,784 with Prime Factorization
| 2 | 974, 944, 714, 784 |
| 2 | 487, 472, 357, 392 |
| 2 | 487, 236, 357, 196 |
| 2 | 487, 118, 357, 98 |
| 7 | 487, 59, 357, 49 |
| 487, 59, 51, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 487 x 59 x 51 x 7 = 1148860272
Therefore, the lowest common multiple of 974,944,714,784 is 1148860272.
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.
974 x 944 x 714 x 784 = 514689401856
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.
974 : 1, 2, 487, 974
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,944,714,784, is 2.
Now, the common factors can be found like this.
974:2x 487
944:2x 2x 2x 2x 59
714:2x 3x 7x 17
784:2x 2x 2x 2x 7x 7
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 7 = 224
Therefore, the value for common factors is 224.
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 = 514689401856/(2x224)
LCM = 514689401856/448
LCM = 1148860272
Thus, we can understand that the LCM of 974,944,714,784 is 1148860272.
