Find LCM of 647,254,669,154,693 with Prime Factorization
| 2 | 647, 254, 669, 154, 693 |
| 3 | 647, 127, 669, 77, 693 |
| 7 | 647, 127, 223, 77, 231 |
| 11 | 647, 127, 223, 11, 33 |
| 647, 127, 223, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 647 x 127 x 223 x 1 x 3 = 25396630182
Therefore, the lowest common multiple of 647,254,669,154,693 is 25396630182.
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.
647 x 254 x 669 x 154 x 693 = 11733243144084
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.
647 : 1, 647
254 : 1, 2, 127, 254
669 : 1, 3, 223, 669
154 : 1, 2, 7, 11, 14, 22, 77, 154
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,254,669,154,693, is 1.
Now, the common factors can be found like this.
647:647
254:2x 127
669:3x 223
154:2x 7x 11
693:3x 3x 7x 11
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 11 = 462
Therefore, the value for common factors is 462.
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 = 11733243144084/(1x462)
LCM = 11733243144084/462
LCM = 25396630182
Thus, we can understand that the LCM of 647,254,669,154,693 is 25396630182.
