Find LCM of 772,917,920,616,392 with Prime Factorization
2 | 772, 917, 920, 616, 392 |
2 | 386, 917, 460, 308, 196 |
2 | 193, 917, 230, 154, 98 |
7 | 193, 917, 115, 77, 49 |
193, 131, 115, 11, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 193 x 131 x 115 x 11 x 7 = 12537334040
Therefore, the lowest common multiple of 772,917,920,616,392 is 12537334040.
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.
772 x 917 x 920 x 616 x 392 = 157268318197760
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.
772 : 1, 2, 4, 193, 386, 772
917 : 1, 7, 131, 917
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,917,920,616,392, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
917:7x 131
920:2x 2x 2x 5x 23
616:2x 2x 2x 7x 11
392:2x 2x 2x 7x 7
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 7x 7 = 12544
Therefore, the value for common factors is 12544.
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 = 157268318197760/(1x12544)
LCM = 157268318197760/12544
LCM = 12537334040
Thus, we can understand that the LCM of 772,917,920,616,392 is 12537334040.
