Given numbers are 649,748,231,862
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,748,231,862 is 399438732.
Find LCM of 649,748,231,862 with Prime Factorization
| 2 | 649, 748, 231, 862 |
| 11 | 649, 374, 231, 431 |
| 59, 34, 21, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 59 x 34 x 21 x 431 = 399438732
Therefore, the lowest common multiple of 649,748,231,862 is 399438732.
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 748 x 231 x 862 = 96664173144
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
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
231 : 1, 3, 7, 11, 21, 33, 77, 231
862 : 1, 2, 431, 862
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,748,231,862, is 1.
Now, the common factors can be found like this.
649:11x 59
748:2x 2x 11x 17
231:3x 7x 11
862:2x 431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 96664173144/(1x242)
LCM = 96664173144/242
LCM = 399438732
Thus, we can understand that the LCM of 649,748,231,862 is 399438732.
