Find LCM of 912,779,748,783,870 with Prime Factorization
| 2 | 912, 779, 748, 783, 870 |
| 2 | 456, 779, 374, 783, 435 |
| 3 | 228, 779, 187, 783, 435 |
| 19 | 76, 779, 187, 261, 145 |
| 29 | 4, 41, 187, 261, 145 |
| 4, 41, 187, 9, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 29 x 4 x 41 x 187 x 9 x 5 = 9124956720
Therefore, the lowest common multiple of 912,779,748,783,870 is 9124956720.
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.
912 x 779 x 748 x 783 x 870 = 362005282995840
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
779 : 1, 19, 41, 779
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
783 : 1, 3, 9, 27, 29, 87, 261, 783
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,779,748,783,870, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
779:19x 41
748:2x 2x 11x 17
783:3x 3x 3x 29
870:2x 3x 5x 29
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 2x 3x 3x 19x 29 = 39672
Therefore, the value for common factors is 39672.
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 = 362005282995840/(1x39672)
LCM = 362005282995840/39672
LCM = 9124956720
Thus, we can understand that the LCM of 912,779,748,783,870 is 9124956720.
