Given numbers are 274,726,942,931,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 274,726,942,931,646 is 247147056618.
Find LCM of 274,726,942,931,646 with Prime Factorization
| 2 | 274, 726, 942, 931, 646 |
| 3 | 137, 363, 471, 931, 323 |
| 19 | 137, 121, 157, 931, 323 |
| 137, 121, 157, 49, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 137 x 121 x 157 x 49 x 17 = 247147056618
Therefore, the lowest common multiple of 274,726,942,931,646 is 247147056618.
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.
274 x 726 x 942 x 931 x 646 = 112699057817808
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.
274 : 1, 2, 137, 274
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
942 : 1, 2, 3, 6, 157, 314, 471, 942
931 : 1, 7, 19, 49, 133, 931
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 274,726,942,931,646, is 1.
Now, the common factors can be found like this.
274:2x 137
726:2x 3x 11x 11
942:2x 3x 157
931:7x 7x 19
646:2x 17x 19
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 19 = 456
Therefore, the value for common factors is 456.
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 = 112699057817808/(1x456)
LCM = 112699057817808/456
LCM = 247147056618
Thus, we can understand that the LCM of 274,726,942,931,646 is 247147056618.
