Find LCM of 649,288,168,671,946 with Prime Factorization
2 | 649, 288, 168, 671, 946 |
2 | 649, 144, 84, 671, 473 |
2 | 649, 72, 42, 671, 473 |
3 | 649, 36, 21, 671, 473 |
11 | 649, 12, 7, 671, 473 |
59, 12, 7, 61, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 59 x 12 x 7 x 61 x 43 = 3431891232
Therefore, the lowest common multiple of 649,288,168,671,946 is 3431891232.
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.
649 x 288 x 168 x 671 x 946 = 19932424275456
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.
649 : 1, 11, 59, 649
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
671 : 1, 11, 61, 671
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,288,168,671,946, is 1.
Now, the common factors can be found like this.
649:11x 59
288:2x 2x 2x 2x 2x 3x 3
168:2x 2x 2x 3x 7
671:11x 61
946:2x 11x 43
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 3x 11x 11 = 5808
Therefore, the value for common factors is 5808.
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 = 19932424275456/(1x5808)
LCM = 19932424275456/5808
LCM = 3431891232
Thus, we can understand that the LCM of 649,288,168,671,946 is 3431891232.
