Given numbers are 857,756,622,646

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 857,756,622,646 is 65082695076.

Find LCM of 857,756,622,646 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 857 x 378 x 311 x 323 = 65082695076

Therefore, the lowest common multiple of 857,756,622,646 is 65082695076.

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.

857 x 756 x 622 x 646 = 260330780304

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.

857 : 1, 857

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

622 : 1, 2, 311, 622

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 857,756,622,646, is 1.

Now, the common factors can be found like this.

857:857

756:2x 2x 3x 3x 3x 7

622:2x 311

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 260330780304/(1x4)

LCM = 260330780304/4

LCM = 65082695076

Thus, we can understand that the LCM of 857,756,622,646 is 65082695076.
