Given numbers are 971,917,393,992

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

The LCM of 971,917,393,992 is 2649851232.

Find LCM of 971,917,393,992 with Prime Factorization

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

131 x 971 x 7 x 3 x 992 = 2649851232

Therefore, the lowest common multiple of 971,917,393,992 is 2649851232.

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.

971 x 917 x 393 x 992 = 347130511392

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.

971 : 1, 971

917 : 1, 7, 131, 917

393 : 1, 3, 131, 393

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,917,393,992, is 1.

Now, the common factors can be found like this.

971:971

917:7x 131

393:3x 131

992:2x 2x 2x 2x 2x 31

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

131 = 131

Therefore, the value for common factors is 131.

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 = 347130511392/(1x131)

LCM = 347130511392/131

LCM = 2649851232

Thus, we can understand that the LCM of 971,917,393,992 is 2649851232.
