Given numbers are 746,668,736,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 746,668,736,561 is 25719704736.
Find LCM of 746,668,736,561 with Prime Factorization
2 | 746, 668, 736, 561 |
2 | 373, 334, 368, 561 |
373, 167, 184, 561 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 373 x 167 x 184 x 561 = 25719704736
Therefore, the lowest common multiple of 746,668,736,561 is 25719704736.
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.
746 x 668 x 736 x 561 = 205757637888
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.
746 : 1, 2, 373, 746
668 : 1, 2, 4, 167, 334, 668
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,668,736,561, is 1.
Now, the common factors can be found like this.
746:2x 373
668:2x 2x 167
736:2x 2x 2x 2x 2x 23
561:3x 11x 17
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 2 = 8
Therefore, the value for common factors is 8.
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 = 205757637888/(1x8)
LCM = 205757637888/8
LCM = 25719704736
Thus, we can understand that the LCM of 746,668,736,561 is 25719704736.
