Given numbers are 991,721,506,291,572
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,721,506,291,572 is 2735431054356.
Find LCM of 991,721,506,291,572 with Prime Factorization
2 | 991, 721, 506, 291, 572 |
11 | 991, 721, 253, 291, 286 |
991, 721, 23, 291, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 991 x 721 x 23 x 291 x 26 = 2735431054356
Therefore, the lowest common multiple of 991,721,506,291,572 is 2735431054356.
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.
991 x 721 x 506 x 291 x 572 = 60179483195832
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.
991 : 1, 991
721 : 1, 7, 103, 721
506 : 1, 2, 11, 22, 23, 46, 253, 506
291 : 1, 3, 97, 291
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,721,506,291,572, is 1.
Now, the common factors can be found like this.
991:991
721:7x 103
506:2x 11x 23
291:3x 97
572:2x 2x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 60179483195832/(1x22)
LCM = 60179483195832/22
LCM = 2735431054356
Thus, we can understand that the LCM of 991,721,506,291,572 is 2735431054356.
