Given numbers are 974,228,857,680,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 974,228,857,680,779 is 663250228440.
Find LCM of 974,228,857,680,779 with Prime Factorization
| 2 | 974, 228, 857, 680, 779 |
| 2 | 487, 114, 857, 340, 779 |
| 19 | 487, 57, 857, 170, 779 |
| 487, 3, 857, 170, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 487 x 3 x 857 x 170 x 41 = 663250228440
Therefore, the lowest common multiple of 974,228,857,680,779 is 663250228440.
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.
974 x 228 x 857 x 680 x 779 = 100814034722880
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.
974 : 1, 2, 487, 974
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
857 : 1, 857
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,228,857,680,779, is 1.
Now, the common factors can be found like this.
974:2x 487
228:2x 2x 3x 19
857:857
680:2x 2x 2x 5x 17
779:19x 41
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 19 = 152
Therefore, the value for common factors is 152.
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 = 100814034722880/(1x152)
LCM = 100814034722880/152
LCM = 663250228440
Thus, we can understand that the LCM of 974,228,857,680,779 is 663250228440.
