Find LCM of 756,393,924,440 with Prime Factorization
2 | 756, 393, 924, 440 |
2 | 378, 393, 462, 220 |
3 | 189, 393, 231, 110 |
7 | 63, 131, 77, 110 |
11 | 9, 131, 11, 110 |
9, 131, 1, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 9 x 131 x 1 x 10 = 10893960
Therefore, the lowest common multiple of 756,393,924,440 is 10893960.
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.
756 x 393 x 924 x 440 = 120792228480
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.
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
393 : 1, 3, 131, 393
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,393,924,440, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
393:3x 131
924:2x 2x 3x 7x 11
440:2x 2x 2x 5x 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 3x 3x 7x 11 = 11088
Therefore, the value for common factors is 11088.
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 = 120792228480/(1x11088)
LCM = 120792228480/11088
LCM = 10893960
Thus, we can understand that the LCM of 756,393,924,440 is 10893960.
