Find LCM of 756,316,814,605,120 with Prime Factorization
| 2 | 756, 316, 814, 605, 120 |
| 2 | 378, 158, 407, 605, 60 |
| 3 | 189, 79, 407, 605, 30 |
| 5 | 63, 79, 407, 605, 10 |
| 11 | 63, 79, 407, 121, 2 |
| 63, 79, 37, 11, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 63 x 79 x 37 x 11 x 2 = 2673843480
Therefore, the lowest common multiple of 756,316,814,605,120 is 2673843480.
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.
756 x 316 x 814 x 605 x 120 = 14117893574400
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.
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
316 : 1, 2, 4, 79, 158, 316
814 : 1, 2, 11, 22, 37, 74, 407, 814
605 : 1, 5, 11, 55, 121, 605
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,316,814,605,120, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
316:2x 2x 79
814:2x 11x 37
605:5x 11x 11
120:2x 2x 2x 3x 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 2x 3x 5x 11 = 5280
Therefore, the value for common factors is 5280.
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 = 14117893574400/(1x5280)
LCM = 14117893574400/5280
LCM = 2673843480
Thus, we can understand that the LCM of 756,316,814,605,120 is 2673843480.
