Given numbers are 671,220,794,964
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,220,794,964 is 1283985340.
Find LCM of 671,220,794,964 with Prime Factorization
| 2 | 671, 220, 794, 964 |
| 2 | 671, 110, 397, 482 |
| 11 | 671, 55, 397, 241 |
| 61, 5, 397, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 61 x 5 x 397 x 241 = 1283985340
Therefore, the lowest common multiple of 671,220,794,964 is 1283985340.
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.
671 x 220 x 794 x 964 = 112990709920
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.
671 : 1, 11, 61, 671
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
794 : 1, 2, 397, 794
964 : 1, 2, 4, 241, 482, 964
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,220,794,964, is 1.
Now, the common factors can be found like this.
671:11x 61
220:2x 2x 5x 11
794:2x 397
964:2x 2x 241
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 11 = 88
Therefore, the value for common factors is 88.
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 = 112990709920/(1x88)
LCM = 112990709920/88
LCM = 1283985340
Thus, we can understand that the LCM of 671,220,794,964 is 1283985340.
