Find LCM of 961,868,609,126 with Prime Factorization
| 2 | 961, 868, 609, 126 |
| 3 | 961, 434, 609, 63 |
| 7 | 961, 434, 203, 21 |
| 31 | 961, 62, 29, 3 |
| 31, 2, 29, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 31 x 31 x 2 x 29 x 3 = 7022988
Therefore, the lowest common multiple of 961,868,609,126 is 7022988.
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.
961 x 868 x 609 x 126 = 64007512632
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.
961 : 1, 31, 961
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
609 : 1, 3, 7, 21, 29, 87, 203, 609
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,868,609,126, is 1.
Now, the common factors can be found like this.
961:31x 31
868:2x 2x 7x 31
609:3x 7x 29
126:2x 3x 3x 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 3x 7x 7x 31 = 9114
Therefore, the value for common factors is 9114.
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 = 64007512632/(1x9114)
LCM = 64007512632/9114
LCM = 7022988
Thus, we can understand that the LCM of 961,868,609,126 is 7022988.
