Find LCM of 667,456,642,644,653 with Prime Factorization
| 2 | 667, 456, 642, 644, 653 |
| 2 | 667, 228, 321, 322, 653 |
| 3 | 667, 114, 321, 161, 653 |
| 23 | 667, 38, 107, 161, 653 |
| 29, 38, 107, 7, 653 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 29 x 38 x 107 x 7 x 653 = 148759830744
Therefore, the lowest common multiple of 667,456,642,644,653 is 148759830744.
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.
667 x 456 x 642 x 644 x 653 = 82115426570688
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.
667 : 1, 23, 29, 667
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
642 : 1, 2, 3, 6, 107, 214, 321, 642
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
653 : 1, 653
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,456,642,644,653, is 1.
Now, the common factors can be found like this.
667:23x 29
456:2x 2x 2x 3x 19
642:2x 3x 107
644:2x 2x 7x 23
653:653
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 3x 23 = 552
Therefore, the value for common factors is 552.
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 = 82115426570688/(1x552)
LCM = 82115426570688/552
LCM = 148759830744
Thus, we can understand that the LCM of 667,456,642,644,653 is 148759830744.
