Given numbers are 427,447,638,694

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

The LCM of 427,447,638,694 is 42255724434.

Find LCM of 427,447,638,694 with Prime Factorization

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

2 x 427 x 447 x 319 x 347 = 42255724434

Therefore, the lowest common multiple of 427,447,638,694 is 42255724434.

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.

427 x 447 x 638 x 694 = 84511448868

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.

427 : 1, 7, 61, 427

447 : 1, 3, 149, 447

638 : 1, 2, 11, 22, 29, 58, 319, 638

694 : 1, 2, 347, 694

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,447,638,694, is 1.

Now, the common factors can be found like this.

427:7x 61

447:3x 149

638:2x 11x 29

694:2x 347

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 = 84511448868/(1x2)

LCM = 84511448868/2

LCM = 42255724434

Thus, we can understand that the LCM of 427,447,638,694 is 42255724434.
