Given numbers are 746,702,398,649,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 746,702,398,649,393 is 4430115129726.
Find LCM of 746,702,398,649,393 with Prime Factorization
2 | 746, 702, 398, 649, 393 |
3 | 373, 351, 199, 649, 393 |
373, 117, 199, 649, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 373 x 117 x 199 x 649 x 131 = 4430115129726
Therefore, the lowest common multiple of 746,702,398,649,393 is 4430115129726.
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 702 x 398 x 649 x 393 = 53161381556712
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
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
398 : 1, 2, 199, 398
649 : 1, 11, 59, 649
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,702,398,649,393, is 1.
Now, the common factors can be found like this.
746:2x 373
702:2x 3x 3x 3x 13
398:2x 199
649:11x 59
393:3x 131
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 3 = 12
Therefore, the value for common factors is 12.
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 = 53161381556712/(1x12)
LCM = 53161381556712/12
LCM = 4430115129726
Thus, we can understand that the LCM of 746,702,398,649,393 is 4430115129726.
