Find LCM of 528,398,921,497,392 with Prime Factorization
| 2 | 528, 398, 921, 497, 392 |
| 2 | 264, 199, 921, 497, 196 |
| 2 | 132, 199, 921, 497, 98 |
| 3 | 66, 199, 921, 497, 49 |
| 7 | 22, 199, 307, 497, 49 |
| 22, 199, 307, 71, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 22 x 199 x 307 x 71 x 7 = 112222464816
Therefore, the lowest common multiple of 528,398,921,497,392 is 112222464816.
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.
528 x 398 x 921 x 497 x 392 = 37706748178176
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.
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
398 : 1, 2, 199, 398
921 : 1, 3, 307, 921
497 : 1, 7, 71, 497
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 528,398,921,497,392, is 1.
Now, the common factors can be found like this.
528:2x 2x 2x 2x 3x 11
398:2x 199
921:3x 307
497:7x 71
392:2x 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 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 37706748178176/(1x336)
LCM = 37706748178176/336
LCM = 112222464816
Thus, we can understand that the LCM of 528,398,921,497,392 is 112222464816.
