Given numbers are 785,278,645,468,703
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,278,645,468,703 is 1543668672780.
Find LCM of 785,278,645,468,703 with Prime Factorization
2 | 785, 278, 645, 468, 703 |
3 | 785, 139, 645, 234, 703 |
5 | 785, 139, 215, 78, 703 |
157, 139, 43, 78, 703 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 157 x 139 x 43 x 78 x 703 = 1543668672780
Therefore, the lowest common multiple of 785,278,645,468,703 is 1543668672780.
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.
785 x 278 x 645 x 468 x 703 = 46310060183400
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.
785 : 1, 5, 157, 785
278 : 1, 2, 139, 278
645 : 1, 3, 5, 15, 43, 129, 215, 645
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,278,645,468,703, is 1.
Now, the common factors can be found like this.
785:5x 157
278:2x 139
645:3x 5x 43
468:2x 2x 3x 3x 13
703:19x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 46310060183400/(1x30)
LCM = 46310060183400/30
LCM = 1543668672780
Thus, we can understand that the LCM of 785,278,645,468,703 is 1543668672780.
