Find LCM of 520,618,656,624 with Prime Factorization
2 | 520, 618, 656, 624 |
2 | 260, 309, 328, 312 |
2 | 130, 309, 164, 156 |
2 | 65, 309, 82, 78 |
3 | 65, 309, 41, 39 |
13 | 65, 103, 41, 13 |
5, 103, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 13 x 5 x 103 x 41 x 1 = 13175760
Therefore, the lowest common multiple of 520,618,656,624 is 13175760.
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.
520 x 618 x 656 x 624 = 131546787840
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
618 : 1, 2, 3, 6, 103, 206, 309, 618
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,618,656,624, is 2.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
618:2x 3x 103
656:2x 2x 2x 2x 41
624:2x 2x 2x 2x 3x 13
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 2x 2x 3x 13 = 4992
Therefore, the value for common factors is 4992.
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 = 131546787840/(2x4992)
LCM = 131546787840/9984
LCM = 13175760
Thus, we can understand that the LCM of 520,618,656,624 is 13175760.
