Given numbers are 61,61,77,66,779

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

The LCM of 61,61,77,66,779 is 21953778.

Find LCM of 61,61,77,66,779 with Prime Factorization

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

11 x 61 x 1 x 1 x 7 x 6 x 779 = 21953778

Therefore, the lowest common multiple of 61,61,77,66,779 is 21953778.

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.

61 x 61 x 77 x 66 x 779 = 14730985038

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.

61 : 1, 61

61 : 1, 61

77 : 1, 7, 11, 77

66 : 1, 2, 3, 6, 11, 22, 33, 66

779 : 1, 19, 41, 779

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 61,61,77,66,779, is 1.

Now, the common factors can be found like this.

61:61

61:61

77:7x 11

66:2x 3x 11

779:19x 41

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

11x 61 = 671

Therefore, the value for common factors is 671.

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 = 14730985038/(1x671)

LCM = 14730985038/671

LCM = 21953778

Thus, we can understand that the LCM of 61,61,77,66,779 is 21953778.
