Given numbers are 940,517,977,987

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

The LCM of 940,517,977,987 is 212145780.

Find LCM of 940,517,977,987 with Prime Factorization

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

47 x 20 x 11 x 977 x 21 = 212145780

Therefore, the lowest common multiple of 940,517,977,987 is 212145780.

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.

940 x 517 x 977 x 987 = 468630028020

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.

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

517 : 1, 11, 47, 517

977 : 1, 977

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 940,517,977,987, is 1.

Now, the common factors can be found like this.

940:2x 2x 5x 47

517:11x 47

977:977

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.

47x 47 = 2209

Therefore, the value for common factors is 2209.

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 = 468630028020/(1x2209)

LCM = 468630028020/2209

LCM = 212145780

Thus, we can understand that the LCM of 940,517,977,987 is 212145780.
