Find LCM of 620,252,651,157 with Prime Factorization
| 2 | 620, 252, 651, 157 |
| 2 | 310, 126, 651, 157 |
| 3 | 155, 63, 651, 157 |
| 7 | 155, 21, 217, 157 |
| 31 | 155, 3, 31, 157 |
| 5, 3, 1, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 31 x 5 x 3 x 1 x 157 = 6132420
Therefore, the lowest common multiple of 620,252,651,157 is 6132420.
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 252 x 651 x 157 = 15968821680
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
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
651 : 1, 3, 7, 21, 31, 93, 217, 651
157 : 1, 157
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,252,651,157, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
252:2x 2x 3x 3x 7
651:3x 7x 31
157:157
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 3x 7x 31 = 2604
Therefore, the value for common factors is 2604.
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 = 15968821680/(1x2604)
LCM = 15968821680/2604
LCM = 6132420
Thus, we can understand that the LCM of 620,252,651,157 is 6132420.
