Find LCM of 906,744,649,385,220 with Prime Factorization
| 2 | 906, 744, 649, 385, 220 |
| 2 | 453, 372, 649, 385, 110 |
| 3 | 453, 186, 649, 385, 55 |
| 5 | 151, 62, 649, 385, 55 |
| 11 | 151, 62, 649, 77, 11 |
| 151, 62, 59, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 151 x 62 x 59 x 7 x 1 = 2551893960
Therefore, the lowest common multiple of 906,744,649,385,220 is 2551893960.
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.
906 x 744 x 649 x 385 x 220 = 37053500299200
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
649 : 1, 11, 59, 649
385 : 1, 5, 7, 11, 35, 55, 77, 385
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,744,649,385,220, is 1.
Now, the common factors can be found like this.
906:2x 3x 151
744:2x 2x 2x 3x 31
649:11x 59
385:5x 7x 11
220:2x 2x 5x 11
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 3x 5x 11x 11 = 14520
Therefore, the value for common factors is 14520.
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 = 37053500299200/(1x14520)
LCM = 37053500299200/14520
LCM = 2551893960
Thus, we can understand that the LCM of 906,744,649,385,220 is 2551893960.
