Given numbers are 785,656,984,710
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,656,984,710 is 109686480.
Find LCM of 785,656,984,710 with Prime Factorization
| 2 | 785, 656, 984, 710 |
| 2 | 785, 328, 492, 355 |
| 2 | 785, 164, 246, 355 |
| 5 | 785, 82, 123, 355 |
| 41 | 157, 82, 123, 71 |
| 157, 2, 3, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 41 x 157 x 2 x 3 x 71 = 109686480
Therefore, the lowest common multiple of 785,656,984,710 is 109686480.
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 656 x 984 x 710 = 359771654400
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
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
710 : 1, 2, 5, 10, 71, 142, 355, 710
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,656,984,710, is 1.
Now, the common factors can be found like this.
785:5x 157
656:2x 2x 2x 2x 41
984:2x 2x 2x 3x 41
710:2x 5x 71
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 5x 41 = 3280
Therefore, the value for common factors is 3280.
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 = 359771654400/(1x3280)
LCM = 359771654400/3280
LCM = 109686480
Thus, we can understand that the LCM of 785,656,984,710 is 109686480.
