The LCM of 627,658,147,979 is 257028618.
Find LCM of 627,658,147,979 with Prime Factorization
| 3 | 627, 658, 147, 979 |
| 7 | 209, 658, 49, 979 |
| 11 | 209, 94, 7, 979 |
| 19, 94, 7, 89 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 19 x 94 x 7 x 89 = 257028618
Therefore, the lowest common multiple of 627,658,147,979 is 257028618.
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.
627 x 658 x 147 x 979 = 59373610758
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.
627 : 1, 3, 11, 19, 33, 57, 209, 627
658 : 1, 2, 7, 14, 47, 94, 329, 658
147 : 1, 3, 7, 21, 49, 147
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 627,658,147,979, is 1.
Now, the common factors can be found like this.
627:3x 11x 19
658:2x 7x 47
147:3x 7x 7
979:11x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 11 = 231
Therefore, the value for common factors is 231.
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 = 59373610758/(1x231)
LCM = 59373610758/231
LCM = 257028618
Thus, we can understand that the LCM of 627,658,147,979 is 257028618.
