Given numbers are 777,128,129,946

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

The LCM of 777,128,129,946 is 47042688.

Find LCM of 777,128,129,946 with Prime Factorization

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

2 x 3 x 43 x 259 x 64 x 1 x 11 = 47042688

Therefore, the lowest common multiple of 777,128,129,946 is 47042688.

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.

777 x 128 x 129 x 946 = 12137013504

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.

777 : 1, 3, 7, 21, 37, 111, 259, 777

128 : 1, 2, 4, 8, 16, 32, 64, 128

129 : 1, 3, 43, 129

946 : 1, 2, 11, 22, 43, 86, 473, 946

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,128,129,946, is 1.

Now, the common factors can be found like this.

777:3x 7x 37

128:2x 2x 2x 2x 2x 2x 2

129:3x 43

946:2x 11x 43

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 43 = 258

Therefore, the value for common factors is 258.

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 = 12137013504/(1x258)

LCM = 12137013504/258

LCM = 47042688

Thus, we can understand that the LCM of 777,128,129,946 is 47042688.
