The LCM of 649,569,287,690,231 is 73128716430.
Find LCM of 649,569,287,690,231 with Prime Factorization
| 3 | 649, 569, 287, 690, 231 |
| 7 | 649, 569, 287, 230, 77 |
| 11 | 649, 569, 41, 230, 11 |
| 59, 569, 41, 230, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 59 x 569 x 41 x 230 x 1 = 73128716430
Therefore, the lowest common multiple of 649,569,287,690,231 is 73128716430.
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.
649 x 569 x 287 x 690 x 231 = 16892733495330
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.
649 : 1, 11, 59, 649
569 : 1, 569
287 : 1, 7, 41, 287
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,569,287,690,231, is 1.
Now, the common factors can be found like this.
649:11x 59
569:569
287:7x 41
690:2x 3x 5x 23
231:3x 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.
3x 7x 11 = 231
Therefore, the value for common factors is 231.
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 = 16892733495330/(1x231)
LCM = 16892733495330/231
LCM = 73128716430
Thus, we can understand that the LCM of 649,569,287,690,231 is 73128716430.
