Given numbers are 658,564,478,781,128
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,564,478,781,128 is 23581751424.
Find LCM of 658,564,478,781,128 with Prime Factorization
| 2 | 658, 564, 478, 781, 128 |
| 2 | 329, 282, 239, 781, 64 |
| 47 | 329, 141, 239, 781, 32 |
| 7, 3, 239, 781, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 47 x 7 x 3 x 239 x 781 x 32 = 23581751424
Therefore, the lowest common multiple of 658,564,478,781,128 is 23581751424.
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.
658 x 564 x 478 x 781 x 128 = 17733477070848
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
478 : 1, 2, 239, 478
781 : 1, 11, 71, 781
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,564,478,781,128, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
564:2x 2x 3x 47
478:2x 239
781:11x 71
128:2x 2x 2x 2x 2x 2x 2
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 2x 47 = 752
Therefore, the value for common factors is 752.
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 = 17733477070848/(1x752)
LCM = 17733477070848/752
LCM = 23581751424
Thus, we can understand that the LCM of 658,564,478,781,128 is 23581751424.
