Given numbers are 713,730,420,734

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

The LCM of 713,730,420,734 is 8022832860.

Find LCM of 713,730,420,734 with Prime Factorization

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

2 x 5 x 713 x 73 x 42 x 367 = 8022832860

Therefore, the lowest common multiple of 713,730,420,734 is 8022832860.

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.

713 x 730 x 420 x 734 = 160456657200

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.

713 : 1, 23, 31, 713

730 : 1, 2, 5, 10, 73, 146, 365, 730

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

734 : 1, 2, 367, 734

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 713,730,420,734, is 1.

Now, the common factors can be found like this.

713:23x 31

730:2x 5x 73

420:2x 2x 3x 5x 7

734:2x 367

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 160456657200/(1x20)

LCM = 160456657200/20

LCM = 8022832860

Thus, we can understand that the LCM of 713,730,420,734 is 8022832860.
