Find LCM of 432,977,672,742 with Prime Factorization
2 | 432, 977, 672, 742 |
2 | 216, 977, 336, 371 |
2 | 108, 977, 168, 371 |
2 | 54, 977, 84, 371 |
3 | 27, 977, 42, 371 |
7 | 9, 977, 14, 371 |
9, 977, 2, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 9 x 977 x 2 x 53 = 313171488
Therefore, the lowest common multiple of 432,977,672,742 is 313171488.
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.
432 x 977 x 672 x 742 = 210451239936
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.
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
977 : 1, 977
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,977,672,742, is 1.
Now, the common factors can be found like this.
432:2x 2x 2x 2x 3x 3x 3
977:977
672:2x 2x 2x 2x 2x 3x 7
742:2x 7x 53
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 3x 7 = 672
Therefore, the value for common factors is 672.
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 = 210451239936/(1x672)
LCM = 210451239936/672
LCM = 313171488
Thus, we can understand that the LCM of 432,977,672,742 is 313171488.
