Find LCM of 916,756,531,980 with Prime Factorization
| 2 | 916, 756, 531, 980 |
| 2 | 458, 378, 531, 490 |
| 3 | 229, 189, 531, 245 |
| 3 | 229, 63, 177, 245 |
| 7 | 229, 21, 59, 245 |
| 229, 3, 59, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 229 x 3 x 59 x 35 = 357501060
Therefore, the lowest common multiple of 916,756,531,980 is 357501060.
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.
916 x 756 x 531 x 980 = 360361068480
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.
916 : 1, 2, 4, 229, 458, 916
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
531 : 1, 3, 9, 59, 177, 531
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,756,531,980, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
756:2x 2x 3x 3x 3x 7
531:3x 3x 59
980:2x 2x 5x 7x 7
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 3x 3x 7 = 1008
Therefore, the value for common factors is 1008.
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 = 360361068480/(1x1008)
LCM = 360361068480/1008
LCM = 357501060
Thus, we can understand that the LCM of 916,756,531,980 is 357501060.
