Given numbers are 123,572,143,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,572,143,715 is 351780.
Find LCM of 123,572,143,715 with Prime Factorization
11 | 123, 572, 143, 715 |
13 | 123, 52, 13, 65 |
123, 4, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 123 x 4 x 1 x 5 = 351780
Therefore, the lowest common multiple of 123,572,143,715 is 351780.
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.
123 x 572 x 143 x 715 = 7193549220
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.
123 : 1, 3, 41, 123
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
143 : 1, 11, 13, 143
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,572,143,715, is 1.
Now, the common factors can be found like this.
123:3x 41
572:2x 2x 11x 13
143:11x 13
715:5x 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.
11x 11x 13x 13 = 20449
Therefore, the value for common factors is 20449.
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 = 7193549220/(1x20449)
LCM = 7193549220/20449
LCM = 351780
Thus, we can understand that the LCM of 123,572,143,715 is 351780.
