Given numbers are 832,715,221,657
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 832,715,221,657 is 511093440.
Find LCM of 832,715,221,657 with Prime Factorization
13 | 832, 715, 221, 657 |
64, 55, 17, 657 |
Multiply the prime numbers at the bottom and the left side.
13 x 64 x 55 x 17 x 657 = 511093440
Therefore, the lowest common multiple of 832,715,221,657 is 511093440.
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.
832 x 715 x 221 x 657 = 86374791360
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.
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
715 : 1, 5, 11, 13, 55, 65, 143, 715
221 : 1, 13, 17, 221
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 832,715,221,657, is 1.
Now, the common factors can be found like this.
832:2x 2x 2x 2x 2x 2x 13
715:5x 11x 13
221:13x 17
657:3x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13 = 169
Therefore, the value for common factors is 169.
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 = 86374791360/(1x169)
LCM = 86374791360/169
LCM = 511093440
Thus, we can understand that the LCM of 832,715,221,657 is 511093440.
