Calculate the LCM of 947,358,669,987

Given numbers are 947,358,669,987

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

The LCM of 947,358,669,987 is 74619961626.

Find LCM of 947,358,669,987 with Prime Factorization


3 947, 358, 669, 987
947, 358, 223, 329

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

3 x 947 x 358 x 223 x 329 = 74619961626

Therefore, the lowest common multiple of 947,358,669,987 is 74619961626.

LCM Formula to Find Lowest Common Multiple of 947,358,669,987

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.

947 x 358 x 669 x 987 = 223859884878

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.

947 : 1, 947

358 : 1, 2, 179, 358

669 : 1, 3, 223, 669

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,358,669,987, is 1.

Now, the common factors can be found like this.

947:947

358:2x 179

669:3x 223

987:3x 7x 47

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

3 = 3

Therefore, the value for common factors is 3.

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 = 223859884878/(1x3)

LCM = 223859884878/3

LCM = 74619961626

Thus, we can understand that the LCM of 947,358,669,987 is 74619961626.
