Given numbers are 642,266,132,657,564
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,266,132,657,564 is 19335318156.
Find LCM of 642,266,132,657,564 with Prime Factorization
| 2 | 642, 266, 132, 657, 564 |
| 2 | 321, 133, 66, 657, 282 |
| 3 | 321, 133, 33, 657, 141 |
| 107, 133, 11, 219, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 107 x 133 x 11 x 219 x 47 = 19335318156
Therefore, the lowest common multiple of 642,266,132,657,564 is 19335318156.
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.
642 x 266 x 132 x 657 x 564 = 8352857443392
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
266 : 1, 2, 7, 14, 19, 38, 133, 266
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
657 : 1, 3, 9, 73, 219, 657
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,266,132,657,564, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
266:2x 7x 19
132:2x 2x 3x 11
657:3x 3x 73
564:2x 2x 3x 47
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 3 = 432
Therefore, the value for common factors is 432.
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 = 8352857443392/(1x432)
LCM = 8352857443392/432
LCM = 19335318156
Thus, we can understand that the LCM of 642,266,132,657,564 is 19335318156.
