Find LCM of 624,644,913,686,637 with Prime Factorization
| 2 | 624, 644, 913, 686, 637 |
| 2 | 312, 322, 913, 343, 637 |
| 7 | 156, 161, 913, 343, 637 |
| 7 | 156, 23, 913, 49, 91 |
| 13 | 156, 23, 913, 7, 13 |
| 12, 23, 913, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 13 x 12 x 23 x 913 x 7 x 1 = 4494457968
Therefore, the lowest common multiple of 624,644,913,686,637 is 4494457968.
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.
624 x 644 x 913 x 686 x 637 = 160326304634496
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
913 : 1, 11, 83, 913
686 : 1, 2, 7, 14, 49, 98, 343, 686
637 : 1, 7, 13, 49, 91, 637
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,644,913,686,637, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
644:2x 2x 7x 23
913:11x 83
686:2x 7x 7x 7
637:7x 7x 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 7x 7x 7x 13 = 35672
Therefore, the value for common factors is 35672.
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 = 160326304634496/(1x35672)
LCM = 160326304634496/35672
LCM = 4494457968
Thus, we can understand that the LCM of 624,644,913,686,637 is 4494457968.
