Given numbers are 468,650,781,142
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 468,650,781,142 is 9137700.
Find LCM of 468,650,781,142 with Prime Factorization
| 2 | 468, 650, 781, 142 |
| 13 | 234, 325, 781, 71 |
| 71 | 18, 25, 781, 71 |
| 18, 25, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 71 x 18 x 25 x 11 x 1 = 9137700
Therefore, the lowest common multiple of 468,650,781,142 is 9137700.
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.
468 x 650 x 781 x 142 = 33736388400
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
781 : 1, 11, 71, 781
142 : 1, 2, 71, 142
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,650,781,142, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
650:2x 5x 5x 13
781:11x 71
142:2x 71
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 71 = 3692
Therefore, the value for common factors is 3692.
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 = 33736388400/(1x3692)
LCM = 33736388400/3692
LCM = 9137700
Thus, we can understand that the LCM of 468,650,781,142 is 9137700.
