Find LCM of 918,231,946,756,620 with Prime Factorization
| 2 | 918, 231, 946, 756, 620 |
| 2 | 459, 231, 473, 378, 310 |
| 3 | 459, 231, 473, 189, 155 |
| 3 | 153, 77, 473, 63, 155 |
| 3 | 51, 77, 473, 21, 155 |
| 7 | 17, 77, 473, 7, 155 |
| 11 | 17, 11, 473, 1, 155 |
| 17, 1, 43, 1, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 7 x 11 x 17 x 1 x 43 x 1 x 155 = 942244380
Therefore, the lowest common multiple of 918,231,946,756,620 is 942244380.
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.
918 x 231 x 946 x 756 x 620 = 94028451168960
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
231 : 1, 3, 7, 11, 21, 33, 77, 231
946 : 1, 2, 11, 22, 43, 86, 473, 946
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
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,231,946,756,620, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
231:3x 7x 11
946:2x 11x 43
756:2x 2x 3x 3x 3x 7
620:2x 2x 5x 31
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 3x 3x 7x 11 = 99792
Therefore, the value for common factors is 99792.
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 = 94028451168960/(1x99792)
LCM = 94028451168960/99792
LCM = 942244380
Thus, we can understand that the LCM of 918,231,946,756,620 is 942244380.
