Find LCM of 307,393,716,657,756 with Prime Factorization
| 2 | 307, 393, 716, 657, 756 |
| 2 | 307, 393, 358, 657, 378 |
| 3 | 307, 393, 179, 657, 189 |
| 3 | 307, 131, 179, 219, 63 |
| 307, 131, 179, 73, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 307 x 131 x 179 x 73 x 21 = 397289747484
Therefore, the lowest common multiple of 307,393,716,657,756 is 397289747484.
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.
307 x 393 x 716 x 657 x 756 = 42907292728272
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.
307 : 1, 307
393 : 1, 3, 131, 393
716 : 1, 2, 4, 179, 358, 716
657 : 1, 3, 9, 73, 219, 657
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,393,716,657,756, is 1.
Now, the common factors can be found like this.
307:307
393:3x 131
716:2x 2x 179
657:3x 3x 73
756:2x 2x 3x 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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 42907292728272/(1x108)
LCM = 42907292728272/108
LCM = 397289747484
Thus, we can understand that the LCM of 307,393,716,657,756 is 397289747484.
