Calculate the LCM of 772,692,878,860

Given numbers are 772,692,878,860

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

The LCM of 772,692,878,860 is 12605683060.

Find LCM of 772,692,878,860 with Prime Factorization


2 772, 692, 878, 860
2 386, 346, 439, 430
193, 173, 439, 215

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

2 x 2 x 193 x 173 x 439 x 215 = 12605683060

Therefore, the lowest common multiple of 772,692,878,860 is 12605683060.

LCM Formula to Find Lowest Common Multiple of 772,692,878,860

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.

772 x 692 x 878 x 860 = 403381857920

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.

772 : 1, 2, 4, 193, 386, 772

692 : 1, 2, 4, 173, 346, 692

878 : 1, 2, 439, 878

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,692,878,860, is 2.

Now, the common factors can be found like this.

772:2x 2x 193

692:2x 2x 173

878:2x 439

860:2x 2x 5x 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 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 403381857920/(2x16)

LCM = 403381857920/32

LCM = 12605683060

Thus, we can understand that the LCM of 772,692,878,860 is 12605683060.
