Find LCM of 279,560,654,721,695 with Prime Factorization
| 2 | 279, 560, 654, 721, 695 |
| 3 | 279, 280, 327, 721, 695 |
| 5 | 93, 280, 109, 721, 695 |
| 7 | 93, 56, 109, 721, 139 |
| 93, 8, 109, 103, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 93 x 8 x 109 x 103 x 139 = 243820800720
Therefore, the lowest common multiple of 279,560,654,721,695 is 243820800720.
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.
279 x 560 x 654 x 721 x 695 = 51202368151200
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.
279 : 1, 3, 9, 31, 93, 279
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
654 : 1, 2, 3, 6, 109, 218, 327, 654
721 : 1, 7, 103, 721
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,560,654,721,695, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
560:2x 2x 2x 2x 5x 7
654:2x 3x 109
721:7x 103
695:5x 139
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 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 51202368151200/(1x210)
LCM = 51202368151200/210
LCM = 243820800720
Thus, we can understand that the LCM of 279,560,654,721,695 is 243820800720.
