Calculate the LCM of 987,356,893,546

Given numbers are 987,356,893,546

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

The LCM of 987,356,893,546 is 86788884.

Find LCM of 987,356,893,546 with Prime Factorization


2 987, 356, 893, 546
3 987, 178, 893, 273
7 329, 178, 893, 91
47 47, 178, 893, 13
1, 178, 19, 13

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

2 x 3 x 7 x 47 x 1 x 178 x 19 x 13 = 86788884

Therefore, the lowest common multiple of 987,356,893,546 is 86788884.

LCM Formula to Find Lowest Common Multiple of 987,356,893,546

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.

987 x 356 x 893 x 546 = 171321257016

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.

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

356 : 1, 2, 4, 89, 178, 356

893 : 1, 19, 47, 893

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,356,893,546, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

356:2x 2x 89

893:19x 47

546:2x 3x 7x 13

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

2x 3x 7x 47 = 1974

Therefore, the value for common factors is 1974.

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 = 171321257016/(1x1974)

LCM = 171321257016/1974

LCM = 86788884

Thus, we can understand that the LCM of 987,356,893,546 is 86788884.
