Find LCM of 930,642,963,568,780 with Prime Factorization
| 2 | 930, 642, 963, 568, 780 |
| 2 | 465, 321, 963, 284, 390 |
| 3 | 465, 321, 963, 142, 195 |
| 5 | 155, 107, 321, 142, 65 |
| 107 | 31, 107, 321, 142, 13 |
| 31, 1, 3, 142, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 107 x 31 x 1 x 3 x 142 x 13 = 1102172760
Therefore, the lowest common multiple of 930,642,963,568,780 is 1102172760.
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.
930 x 642 x 963 x 568 x 780 = 254734168291200
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.
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
642 : 1, 2, 3, 6, 107, 214, 321, 642
963 : 1, 3, 9, 107, 321, 963
568 : 1, 2, 4, 8, 71, 142, 284, 568
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 930,642,963,568,780, is 1.
Now, the common factors can be found like this.
930:2x 3x 5x 31
642:2x 3x 107
963:3x 3x 107
568:2x 2x 2x 71
780:2x 2x 3x 5x 13
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 5x 107 = 231120
Therefore, the value for common factors is 231120.
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 = 254734168291200/(1x231120)
LCM = 254734168291200/231120
LCM = 1102172760
Thus, we can understand that the LCM of 930,642,963,568,780 is 1102172760.
