Find LCM of 620,275,625,916,657 with Prime Factorization
| 2 | 620, 275, 625, 916, 657 |
| 2 | 310, 275, 625, 458, 657 |
| 5 | 155, 275, 625, 229, 657 |
| 5 | 31, 55, 125, 229, 657 |
| 31, 11, 25, 229, 657 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 31 x 11 x 25 x 229 x 657 = 128261182500
Therefore, the lowest common multiple of 620,275,625,916,657 is 128261182500.
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.
620 x 275 x 625 x 916 x 657 = 64130591250000
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
275 : 1, 5, 11, 25, 55, 275
625 : 1, 5, 25, 125, 625
916 : 1, 2, 4, 229, 458, 916
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,275,625,916,657, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
275:5x 5x 11
625:5x 5x 5x 5
916:2x 2x 229
657:3x 3x 73
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 5x 5x 5 = 500
Therefore, the value for common factors is 500.
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 = 64130591250000/(1x500)
LCM = 64130591250000/500
LCM = 128261182500
Thus, we can understand that the LCM of 620,275,625,916,657 is 128261182500.
