Given numbers are 625,979,361,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 625,979,361,646 is 7510153750.
Find LCM of 625,979,361,646 with Prime Factorization
19 | 625, 979, 361, 646 |
625, 979, 19, 34 |
Multiply the prime numbers at the bottom and the left side.
19 x 625 x 979 x 19 x 34 = 7510153750
Therefore, the lowest common multiple of 625,979,361,646 is 7510153750.
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.
625 x 979 x 361 x 646 = 142692921250
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.
625 : 1, 5, 25, 125, 625
979 : 1, 11, 89, 979
361 : 1, 19, 361
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 625,979,361,646, is 1.
Now, the common factors can be found like this.
625:5x 5x 5x 5
979:11x 89
361:19x 19
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 142692921250/(1x19)
LCM = 142692921250/19
LCM = 7510153750
Thus, we can understand that the LCM of 625,979,361,646 is 7510153750.
