Find LCM of 156,842,720,772,432 with Prime Factorization
2 | 156, 842, 720, 772, 432 |
2 | 78, 421, 360, 386, 216 |
2 | 39, 421, 180, 193, 108 |
2 | 39, 421, 90, 193, 54 |
3 | 39, 421, 45, 193, 27 |
3 | 13, 421, 15, 193, 9 |
13, 421, 5, 193, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 13 x 421 x 5 x 193 x 3 = 2281584240
Therefore, the lowest common multiple of 156,842,720,772,432 is 2281584240.
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.
156 x 842 x 720 x 772 x 432 = 31540620533760
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
842 : 1, 2, 421, 842
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
772 : 1, 2, 4, 193, 386, 772
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,842,720,772,432, is 2.
Now, the common factors can be found like this.
156:2x 2x 3x 13
842:2x 421
720:2x 2x 2x 2x 3x 3x 5
772:2x 2x 193
432:2x 2x 2x 2x 3x 3x 3
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 2x 2x 3x 3x 3 = 6912
Therefore, the value for common factors is 6912.
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 = 31540620533760/(2x6912)
LCM = 31540620533760/13824
LCM = 2281584240
Thus, we can understand that the LCM of 156,842,720,772,432 is 2281584240.
