Given numbers are 628,851,828,284,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,851,828,284,688 is 58737912624.
Find LCM of 628,851,828,284,688 with Prime Factorization
| 2 | 628, 851, 828, 284, 688 |
| 2 | 314, 851, 414, 142, 344 |
| 23 | 157, 851, 207, 71, 172 |
| 157, 37, 9, 71, 172 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 157 x 37 x 9 x 71 x 172 = 58737912624
Therefore, the lowest common multiple of 628,851,828,284,688 is 58737912624.
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 851 x 828 x 284 x 688 = 86462207382528
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
851 : 1, 23, 37, 851
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
284 : 1, 2, 4, 71, 142, 284
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,851,828,284,688, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
851:23x 37
828:2x 2x 3x 3x 23
284:2x 2x 71
688:2x 2x 2x 2x 43
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 2x 2x 23 = 1472
Therefore, the value for common factors is 1472.
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 = 86462207382528/(1x1472)
LCM = 86462207382528/1472
LCM = 58737912624
Thus, we can understand that the LCM of 628,851,828,284,688 is 58737912624.
