Given numbers are 851,756,736,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,756,736,100 is 128671200.
Find LCM of 851,756,736,100 with Prime Factorization
| 2 | 851, 756, 736, 100 |
| 2 | 851, 378, 368, 50 |
| 23 | 851, 189, 184, 25 |
| 37, 189, 8, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 37 x 189 x 8 x 25 = 128671200
Therefore, the lowest common multiple of 851,756,736,100 is 128671200.
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.
851 x 756 x 736 x 100 = 47351001600
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.
851 : 1, 23, 37, 851
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,756,736,100, is 1.
Now, the common factors can be found like this.
851:23x 37
756:2x 2x 3x 3x 3x 7
736:2x 2x 2x 2x 2x 23
100:2x 2x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 23 = 368
Therefore, the value for common factors is 368.
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 = 47351001600/(1x368)
LCM = 47351001600/368
LCM = 128671200
Thus, we can understand that the LCM of 851,756,736,100 is 128671200.
