Find LCM of 644,492,399,913,957 with Prime Factorization
2 | 644, 492, 399, 913, 957 |
2 | 322, 246, 399, 913, 957 |
3 | 161, 123, 399, 913, 957 |
7 | 161, 41, 133, 913, 319 |
11 | 23, 41, 19, 913, 319 |
23, 41, 19, 83, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 23 x 41 x 19 x 83 x 29 = 39848626356
Therefore, the lowest common multiple of 644,492,399,913,957 is 39848626356.
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.
644 x 492 x 399 x 913 x 957 = 110460392258832
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
399 : 1, 3, 7, 19, 21, 57, 133, 399
913 : 1, 11, 83, 913
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,492,399,913,957, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
492:2x 2x 3x 41
399:3x 7x 19
913:11x 83
957:3x 11x 29
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 3x 3x 7x 11 = 2772
Therefore, the value for common factors is 2772.
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 = 110460392258832/(1x2772)
LCM = 110460392258832/2772
LCM = 39848626356
Thus, we can understand that the LCM of 644,492,399,913,957 is 39848626356.
