Given numbers are 942,748,520,787
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 942,748,520,787 is 36044631480.
Find LCM of 942,748,520,787 with Prime Factorization
| 2 | 942, 748, 520, 787 |
| 2 | 471, 374, 260, 787 |
| 471, 187, 130, 787 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 471 x 187 x 130 x 787 = 36044631480
Therefore, the lowest common multiple of 942,748,520,787 is 36044631480.
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.
942 x 748 x 520 x 787 = 288357051840
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
787 : 1, 787
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,748,520,787, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
748:2x 2x 11x 17
520:2x 2x 2x 5x 13
787:787
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 2 = 8
Therefore, the value for common factors is 8.
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 = 288357051840/(1x8)
LCM = 288357051840/8
LCM = 36044631480
Thus, we can understand that the LCM of 942,748,520,787 is 36044631480.
