Given numbers are 628,572,781,297
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,572,781,297 is 172154268.
Find LCM of 628,572,781,297 with Prime Factorization
| 2 | 628, 572, 781, 297 |
| 2 | 314, 286, 781, 297 |
| 11 | 157, 143, 781, 297 |
| 157, 13, 71, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 157 x 13 x 71 x 27 = 172154268
Therefore, the lowest common multiple of 628,572,781,297 is 172154268.
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.
628 x 572 x 781 x 297 = 83322665712
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.
628 : 1, 2, 4, 157, 314, 628
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
781 : 1, 11, 71, 781
297 : 1, 3, 9, 11, 27, 33, 99, 297
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,572,781,297, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
572:2x 2x 11x 13
781:11x 71
297:3x 3x 3x 11
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 83322665712/(1x484)
LCM = 83322665712/484
LCM = 172154268
Thus, we can understand that the LCM of 628,572,781,297 is 172154268.
