Given numbers are 707,671,836,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 707,671,836,220 is 180270860.
Find LCM of 707,671,836,220 with Prime Factorization
| 2 | 707, 671, 836, 220 |
| 2 | 707, 671, 418, 110 |
| 11 | 707, 671, 209, 55 |
| 707, 61, 19, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 707 x 61 x 19 x 5 = 180270860
Therefore, the lowest common multiple of 707,671,836,220 is 180270860.
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.
707 x 671 x 836 x 220 = 87251096240
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.
707 : 1, 7, 101, 707
671 : 1, 11, 61, 671
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,671,836,220, is 1.
Now, the common factors can be found like this.
707:7x 101
671:11x 61
836:2x 2x 11x 19
220:2x 2x 5x 11
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 87251096240/(1x484)
LCM = 87251096240/484
LCM = 180270860
Thus, we can understand that the LCM of 707,671,836,220 is 180270860.
