Calculate the LCM of 661,766,477,347,680

Given numbers are 661,766,477,347,680

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

The LCM of 661,766,477,347,680 is 28494234885960.

Find LCM of 661,766,477,347,680 with Prime Factorization


2 661, 766, 477, 347, 680
661, 383, 477, 347, 340

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

2 x 661 x 383 x 477 x 347 x 340 = 28494234885960

Therefore, the lowest common multiple of 661,766,477,347,680 is 28494234885960.

LCM Formula to Find Lowest Common Multiple of 661,766,477,347,680

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.

661 x 766 x 477 x 347 x 680 = 56988469771920

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.

661 : 1, 661

766 : 1, 2, 383, 766

477 : 1, 3, 9, 53, 159, 477

347 : 1, 347

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,766,477,347,680, is 1.

Now, the common factors can be found like this.

661:661

766:2x 383

477:3x 3x 53

347:347

680:2x 2x 2x 5x 17

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

2 = 2

Therefore, the value for common factors is 2.

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 = 56988469771920/(1x2)

LCM = 56988469771920/2

LCM = 28494234885960

Thus, we can understand that the LCM of 661,766,477,347,680 is 28494234885960.
