Find LCM of 921,688,577,730,252 with Prime Factorization
| 2 | 921, 688, 577, 730, 252 |
| 2 | 921, 344, 577, 365, 126 |
| 3 | 921, 172, 577, 365, 63 |
| 307, 172, 577, 365, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 307 x 172 x 577 x 365 x 21 = 2802438177840
Therefore, the lowest common multiple of 921,688,577,730,252 is 2802438177840.
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.
921 x 688 x 577 x 730 x 252 = 67258516268160
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.
921 : 1, 3, 307, 921
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
577 : 1, 577
730 : 1, 2, 5, 10, 73, 146, 365, 730
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,688,577,730,252, is 1.
Now, the common factors can be found like this.
921:3x 307
688:2x 2x 2x 2x 43
577:577
730:2x 5x 73
252:2x 2x 3x 3x 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 3 = 24
Therefore, the value for common factors is 24.
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 = 67258516268160/(1x24)
LCM = 67258516268160/24
LCM = 2802438177840
Thus, we can understand that the LCM of 921,688,577,730,252 is 2802438177840.
