The LCM of 640,654,723,776,667 is 3263189819520.
Find LCM of 640,654,723,776,667 with Prime Factorization
| 2 | 640, 654, 723, 776, 667 |
| 2 | 320, 327, 723, 388, 667 |
| 2 | 160, 327, 723, 194, 667 |
| 3 | 80, 327, 723, 97, 667 |
| 80, 109, 241, 97, 667 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 80 x 109 x 241 x 97 x 667 = 3263189819520
Therefore, the lowest common multiple of 640,654,723,776,667 is 3263189819520.
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.
640 x 654 x 723 x 776 x 667 = 156633111336960
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
654 : 1, 2, 3, 6, 109, 218, 327, 654
723 : 1, 3, 241, 723
776 : 1, 2, 4, 8, 97, 194, 388, 776
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,654,723,776,667, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
654:2x 3x 109
723:3x 241
776:2x 2x 2x 97
667:23x 29
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 3 = 48
Therefore, the value for common factors is 48.
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 = 156633111336960/(1x48)
LCM = 156633111336960/48
LCM = 3263189819520
Thus, we can understand that the LCM of 640,654,723,776,667 is 3263189819520.
