Find LCM of 812,646,321,152,640 with Prime Factorization
2 | 812, 646, 321, 152, 640 |
2 | 406, 323, 321, 76, 320 |
2 | 203, 323, 321, 38, 160 |
19 | 203, 323, 321, 19, 80 |
203, 17, 321, 1, 80 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 203 x 17 x 321 x 1 x 80 = 13470495360
Therefore, the lowest common multiple of 812,646,321,152,640 is 13470495360.
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.
812 x 646 x 321 x 152 x 640 = 16380122357760
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
646 : 1, 2, 17, 19, 34, 38, 323, 646
321 : 1, 3, 107, 321
152 : 1, 2, 4, 8, 19, 38, 76, 152
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,646,321,152,640, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
646:2x 17x 19
321:3x 107
152:2x 2x 2x 19
640:2x 2x 2x 2x 2x 2x 2x 5
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 19 = 1216
Therefore, the value for common factors is 1216.
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 = 16380122357760/(1x1216)
LCM = 16380122357760/1216
LCM = 13470495360
Thus, we can understand that the LCM of 812,646,321,152,640 is 13470495360.
