Given numbers are 785,637,905,110
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,637,905,110 is 1991179190.
Find LCM of 785,637,905,110 with Prime Factorization
| 5 | 785, 637, 905, 110 |
| 157, 637, 181, 22 |
Multiply the prime numbers at the bottom and the left side.
5 x 157 x 637 x 181 x 22 = 1991179190
Therefore, the lowest common multiple of 785,637,905,110 is 1991179190.
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 637 x 905 x 110 = 49779479750
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
637 : 1, 7, 13, 49, 91, 637
905 : 1, 5, 181, 905
110 : 1, 2, 5, 10, 11, 22, 55, 110
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,637,905,110, is 1.
Now, the common factors can be found like this.
785:5x 157
637:7x 7x 13
905:5x 181
110:2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5 = 25
Therefore, the value for common factors is 25.
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 = 49779479750/(1x25)
LCM = 49779479750/25
LCM = 1991179190
Thus, we can understand that the LCM of 785,637,905,110 is 1991179190.
