Find LCM of 776,845,300,561,643 with Prime Factorization
2 | 776, 845, 300, 561, 643 |
2 | 388, 845, 150, 561, 643 |
3 | 194, 845, 75, 561, 643 |
5 | 194, 845, 25, 187, 643 |
194, 169, 5, 187, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 194 x 169 x 5 x 187 x 643 = 1182666427800
Therefore, the lowest common multiple of 776,845,300,561,643 is 1182666427800.
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.
776 x 845 x 300 x 561 x 643 = 70959985668000
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.
776 : 1, 2, 4, 8, 97, 194, 388, 776
845 : 1, 5, 13, 65, 169, 845
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
561 : 1, 3, 11, 17, 33, 51, 187, 561
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 776,845,300,561,643, is 1.
Now, the common factors can be found like this.
776:2x 2x 2x 97
845:5x 13x 13
300:2x 2x 3x 5x 5
561:3x 11x 17
643:643
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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 70959985668000/(1x60)
LCM = 70959985668000/60
LCM = 1182666427800
Thus, we can understand that the LCM of 776,845,300,561,643 is 1182666427800.
