Given numbers are 946,968,497,781

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

The LCM of 946,968,497,781 is 20687128.

Find LCM of 946,968,497,781 with Prime Factorization

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

2 x 11 x 71 x 43 x 44 x 7 x 1 = 20687128

Therefore, the lowest common multiple of 946,968,497,781 is 20687128.

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.

946 x 968 x 497 x 781 = 355446233296

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.

946 : 1, 2, 11, 22, 43, 86, 473, 946

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

497 : 1, 7, 71, 497

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,968,497,781, is 1.

Now, the common factors can be found like this.

946:2x 11x 43

968:2x 2x 2x 11x 11

497:7x 71

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.

2x 11x 11x 71 = 17182

Therefore, the value for common factors is 17182.

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 = 355446233296/(1x17182)

LCM = 355446233296/17182

LCM = 20687128

Thus, we can understand that the LCM of 946,968,497,781 is 20687128.
