Given numbers are 971,407,628,785

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

The LCM of 971,407,628,785 is 1240918580.

Find LCM of 971,407,628,785 with Prime Factorization

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

157 x 971 x 407 x 4 x 5 = 1240918580

Therefore, the lowest common multiple of 971,407,628,785 is 1240918580.

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 407 x 628 x 785 = 194824217060

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

407 : 1, 11, 37, 407

628 : 1, 2, 4, 157, 314, 628

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,407,628,785, is 1.

Now, the common factors can be found like this.

971:971

407:11x 37

628:2x 2x 157

785:5x 157

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

157 = 157

Therefore, the value for common factors is 157.

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 = 194824217060/(1x157)

LCM = 194824217060/157

LCM = 1240918580

Thus, we can understand that the LCM of 971,407,628,785 is 1240918580.
