Given numbers are 676,572,641,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,572,641,947 is 4513852772.
Find LCM of 676,572,641,947 with Prime Factorization
| 2 | 676, 572, 641, 947 |
| 2 | 338, 286, 641, 947 |
| 13 | 169, 143, 641, 947 |
| 13, 11, 641, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 13 x 11 x 641 x 947 = 4513852772
Therefore, the lowest common multiple of 676,572,641,947 is 4513852772.
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.
676 x 572 x 641 x 947 = 234720344144
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
641 : 1, 641
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,572,641,947, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
572:2x 2x 11x 13
641:641
947:947
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 13 = 52
Therefore, the value for common factors is 52.
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 = 234720344144/(1x52)
LCM = 234720344144/52
LCM = 4513852772
Thus, we can understand that the LCM of 676,572,641,947 is 4513852772.
