The LCM of 654,649,946,763,140 is 1277582460.
Find LCM of 654,649,946,763,140 with Prime Factorization
| 2 | 654, 649, 946, 763, 140 |
| 7 | 327, 649, 473, 763, 70 |
| 11 | 327, 649, 473, 109, 10 |
| 109 | 327, 59, 43, 109, 10 |
| 3, 59, 43, 1, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 109 x 3 x 59 x 43 x 1 x 10 = 1277582460
Therefore, the lowest common multiple of 654,649,946,763,140 is 1277582460.
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.
654 x 649 x 946 x 763 x 140 = 42890998347120
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
649 : 1, 11, 59, 649
946 : 1, 2, 11, 22, 43, 86, 473, 946
763 : 1, 7, 109, 763
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,649,946,763,140, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
649:11x 59
946:2x 11x 43
763:7x 109
140:2x 2x 5x 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 7x 11x 109 = 33572
Therefore, the value for common factors is 33572.
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 = 42890998347120/(1x33572)
LCM = 42890998347120/33572
LCM = 1277582460
Thus, we can understand that the LCM of 654,649,946,763,140 is 1277582460.
