Given numbers are 491,637,713,175,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 491,637,713,175,690 is 33450430650.
Find LCM of 491,637,713,175,690 with Prime Factorization
5 | 491, 637, 713, 175, 690 |
7 | 491, 637, 713, 35, 138 |
23 | 491, 91, 713, 5, 138 |
491, 91, 31, 5, 6 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 23 x 491 x 91 x 31 x 5 x 6 = 33450430650
Therefore, the lowest common multiple of 491,637,713,175,690 is 33450430650.
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.
491 x 637 x 713 x 175 x 690 = 26927596673250
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.
491 : 1, 491
637 : 1, 7, 13, 49, 91, 637
713 : 1, 23, 31, 713
175 : 1, 5, 7, 25, 35, 175
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,637,713,175,690, is 1.
Now, the common factors can be found like this.
491:491
637:7x 7x 13
713:23x 31
175:5x 5x 7
690:2x 3x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 23 = 805
Therefore, the value for common factors is 805.
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 = 26927596673250/(1x805)
LCM = 26927596673250/805
LCM = 33450430650
Thus, we can understand that the LCM of 491,637,713,175,690 is 33450430650.
