Find LCM of 657,465,137,279,160 with Prime Factorization
| 3 | 657, 465, 137, 279, 160 |
| 3 | 219, 155, 137, 93, 160 |
| 5 | 73, 155, 137, 31, 160 |
| 31 | 73, 31, 137, 31, 32 |
| 73, 1, 137, 1, 32 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 31 x 73 x 1 x 137 x 1 x 32 = 446444640
Therefore, the lowest common multiple of 657,465,137,279,160 is 446444640.
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.
657 x 465 x 137 x 279 x 160 = 1868370818400
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.
657 : 1, 3, 9, 73, 219, 657
465 : 1, 3, 5, 15, 31, 93, 155, 465
137 : 1, 137
279 : 1, 3, 9, 31, 93, 279
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,465,137,279,160, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
465:3x 5x 31
137:137
279:3x 3x 31
160:2x 2x 2x 2x 2x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 31 = 4185
Therefore, the value for common factors is 4185.
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 = 1868370818400/(1x4185)
LCM = 1868370818400/4185
LCM = 446444640
Thus, we can understand that the LCM of 657,465,137,279,160 is 446444640.
