Given numbers are 422,973,974,781

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

The LCM of 422,973,974,781 is 156172760282.

Find LCM of 422,973,974,781 with Prime Factorization

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

2 x 211 x 973 x 487 x 781 = 156172760282

Therefore, the lowest common multiple of 422,973,974,781 is 156172760282.

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.

422 x 973 x 974 x 781 = 312345520564

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.

422 : 1, 2, 211, 422

973 : 1, 7, 139, 973

974 : 1, 2, 487, 974

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,973,974,781, is 1.

Now, the common factors can be found like this.

422:2x 211

973:7x 139

974:2x 487

781:11x 71

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

2 = 2

Therefore, the value for common factors is 2.

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 = 312345520564/(1x2)

LCM = 312345520564/2

LCM = 156172760282

Thus, we can understand that the LCM of 422,973,974,781 is 156172760282.
