Given numbers are 649,472,657,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,472,657,771 is 876664008.
Find LCM of 649,472,657,771 with Prime Factorization
| 3 | 649, 472, 657, 771 |
| 59 | 649, 472, 219, 257 |
| 11, 8, 219, 257 |
Multiply the prime numbers at the bottom and the left side.
3 x 59 x 11 x 8 x 219 x 257 = 876664008
Therefore, the lowest common multiple of 649,472,657,771 is 876664008.
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 472 x 657 x 771 = 155169529416
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
472 : 1, 2, 4, 8, 59, 118, 236, 472
657 : 1, 3, 9, 73, 219, 657
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,472,657,771, is 1.
Now, the common factors can be found like this.
649:11x 59
472:2x 2x 2x 59
657:3x 3x 73
771:3x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 59 = 177
Therefore, the value for common factors is 177.
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 = 155169529416/(1x177)
LCM = 155169529416/177
LCM = 876664008
Thus, we can understand that the LCM of 649,472,657,771 is 876664008.
