Given numbers are 963,429,160,121,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 963,429,160,121,646 is 78284812320.
Find LCM of 963,429,160,121,646 with Prime Factorization
2 | 963, 429, 160, 121, 646 |
3 | 963, 429, 80, 121, 323 |
11 | 321, 143, 80, 121, 323 |
321, 13, 80, 11, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 321 x 13 x 80 x 11 x 323 = 78284812320
Therefore, the lowest common multiple of 963,429,160,121,646 is 78284812320.
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.
963 x 429 x 160 x 121 x 646 = 5166797613120
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.
963 : 1, 3, 9, 107, 321, 963
429 : 1, 3, 11, 13, 33, 39, 143, 429
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
121 : 1, 11, 121
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 963,429,160,121,646, is 1.
Now, the common factors can be found like this.
963:3x 3x 107
429:3x 11x 13
160:2x 2x 2x 2x 2x 5
121:11x 11
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 5166797613120/(1x66)
LCM = 5166797613120/66
LCM = 78284812320
Thus, we can understand that the LCM of 963,429,160,121,646 is 78284812320.
