Find LCM of 779,572,728,171 with Prime Factorization
| 2 | 779, 572, 728, 171 |
| 2 | 779, 286, 364, 171 |
| 13 | 779, 143, 182, 171 |
| 19 | 779, 11, 14, 171 |
| 41, 11, 14, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 41 x 11 x 14 x 9 = 56144088
Therefore, the lowest common multiple of 779,572,728,171 is 56144088.
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.
779 x 572 x 728 x 171 = 55470358944
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.
779 : 1, 19, 41, 779
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,572,728,171, is 1.
Now, the common factors can be found like this.
779:19x 41
572:2x 2x 11x 13
728:2x 2x 2x 7x 13
171:3x 3x 19
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 13x 19 = 988
Therefore, the value for common factors is 988.
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 = 55470358944/(1x988)
LCM = 55470358944/988
LCM = 56144088
Thus, we can understand that the LCM of 779,572,728,171 is 56144088.
