Given numbers are 77,56,81,359

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

The LCM of 77,56,81,359 is 17912664.

Find LCM of 77,56,81,359 with Prime Factorization

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

7 x 11 x 8 x 81 x 359 = 17912664

Therefore, the lowest common multiple of 77,56,81,359 is 17912664.

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.

77 x 56 x 81 x 359 = 125388648

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.

77 : 1, 7, 11, 77

56 : 1, 2, 4, 7, 8, 14, 28, 56

81 : 1, 3, 9, 27, 81

359 : 1, 359

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 77,56,81,359, is 1.

Now, the common factors can be found like this.

77:7x 11

56:2x 2x 2x 7

81:3x 3x 3x 3

359:359

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

7 = 7

Therefore, the value for common factors is 7.

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 = 125388648/(1x7)

LCM = 125388648/7

LCM = 17912664

Thus, we can understand that the LCM of 77,56,81,359 is 17912664.
