Given numbers are 103,686,473,765,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 103,686,473,765,748 is 51134488020.
Find LCM of 103,686,473,765,748 with Prime Factorization
| 2 | 103, 686, 473, 765, 748 |
| 11 | 103, 343, 473, 765, 374 |
| 17 | 103, 343, 43, 765, 34 |
| 103, 343, 43, 45, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 103 x 343 x 43 x 45 x 2 = 51134488020
Therefore, the lowest common multiple of 103,686,473,765,748 is 51134488020.
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.
103 x 686 x 473 x 765 x 748 = 19124298519480
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.
103 : 1, 103
686 : 1, 2, 7, 14, 49, 98, 343, 686
473 : 1, 11, 43, 473
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,686,473,765,748, is 1.
Now, the common factors can be found like this.
103:103
686:2x 7x 7x 7
473:11x 43
765:3x 3x 5x 17
748:2x 2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 17 = 374
Therefore, the value for common factors is 374.
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 = 19124298519480/(1x374)
LCM = 19124298519480/374
LCM = 51134488020
Thus, we can understand that the LCM of 103,686,473,765,748 is 51134488020.
