Given numbers are 930,657,646,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 930,657,646,974 is 32037494670.
Find LCM of 930,657,646,974 with Prime Factorization
| 2 | 930, 657, 646, 974 |
| 3 | 465, 657, 323, 487 |
| 155, 219, 323, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 155 x 219 x 323 x 487 = 32037494670
Therefore, the lowest common multiple of 930,657,646,974 is 32037494670.
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.
930 x 657 x 646 x 974 = 384449936040
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.
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
657 : 1, 3, 9, 73, 219, 657
646 : 1, 2, 17, 19, 34, 38, 323, 646
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 930,657,646,974, is 1.
Now, the common factors can be found like this.
930:2x 3x 5x 31
657:3x 3x 73
646:2x 17x 19
974:2x 487
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 3 = 12
Therefore, the value for common factors is 12.
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 = 384449936040/(1x12)
LCM = 384449936040/12
LCM = 32037494670
Thus, we can understand that the LCM of 930,657,646,974 is 32037494670.
