Find LCM of 472,391,628,767,644 with Prime Factorization
| 2 | 472, 391, 628, 767, 644 |
| 2 | 236, 391, 314, 767, 322 |
| 23 | 118, 391, 157, 767, 161 |
| 59 | 118, 17, 157, 767, 7 |
| 2, 17, 157, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 59 x 2 x 17 x 157 x 13 x 7 = 2636694424
Therefore, the lowest common multiple of 472,391,628,767,644 is 2636694424.
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.
472 x 391 x 628 x 767 x 644 = 57247909333888
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.
472 : 1, 2, 4, 8, 59, 118, 236, 472
391 : 1, 17, 23, 391
628 : 1, 2, 4, 157, 314, 628
767 : 1, 13, 59, 767
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 472,391,628,767,644, is 1.
Now, the common factors can be found like this.
472:2x 2x 2x 59
391:17x 23
628:2x 2x 157
767:13x 59
644:2x 2x 7x 23
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 23x 59 = 21712
Therefore, the value for common factors is 21712.
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 = 57247909333888/(1x21712)
LCM = 57247909333888/21712
LCM = 2636694424
Thus, we can understand that the LCM of 472,391,628,767,644 is 2636694424.
