Given numbers are 658,572,781,235
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,572,781,235 is 66806740.
Find LCM of 658,572,781,235 with Prime Factorization
| 2 | 658, 572, 781, 235 |
| 11 | 329, 286, 781, 235 |
| 47 | 329, 26, 71, 235 |
| 7, 26, 71, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 47 x 7 x 26 x 71 x 5 = 66806740
Therefore, the lowest common multiple of 658,572,781,235 is 66806740.
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 572 x 781 x 235 = 69078169160
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
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
781 : 1, 11, 71, 781
235 : 1, 5, 47, 235
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,572,781,235, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
572:2x 2x 11x 13
781:11x 71
235:5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 47 = 1034
Therefore, the value for common factors is 1034.
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 = 69078169160/(1x1034)
LCM = 69078169160/1034
LCM = 66806740
Thus, we can understand that the LCM of 658,572,781,235 is 66806740.
