Find LCM of 642,555,893,665,332 with Prime Factorization
| 2 | 642, 555, 893, 665, 332 |
| 3 | 321, 555, 893, 665, 166 |
| 5 | 107, 185, 893, 665, 166 |
| 19 | 107, 37, 893, 133, 166 |
| 107, 37, 47, 7, 166 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 107 x 37 x 47 x 7 x 166 = 123243590820
Therefore, the lowest common multiple of 642,555,893,665,332 is 123243590820.
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 555 x 893 x 665 x 332 = 70248846767400
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
555 : 1, 3, 5, 15, 37, 111, 185, 555
893 : 1, 19, 47, 893
665 : 1, 5, 7, 19, 35, 95, 133, 665
332 : 1, 2, 4, 83, 166, 332
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,555,893,665,332, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
555:3x 5x 37
893:19x 47
665:5x 7x 19
332:2x 2x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 19 = 570
Therefore, the value for common factors is 570.
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 = 70248846767400/(1x570)
LCM = 70248846767400/570
LCM = 123243590820
Thus, we can understand that the LCM of 642,555,893,665,332 is 123243590820.
