Given numbers are 772,724,630,172

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

The LCM of 772,724,630,172 is 1892669940.

Find LCM of 772,724,630,172 with Prime Factorization

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

2 x 2 x 193 x 181 x 315 x 43 = 1892669940

Therefore, the lowest common multiple of 772,724,630,172 is 1892669940.

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.

772 x 724 x 630 x 172 = 60565438080

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.

772 : 1, 2, 4, 193, 386, 772

724 : 1, 2, 4, 181, 362, 724

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

172 : 1, 2, 4, 43, 86, 172

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,724,630,172, is 2.

Now, the common factors can be found like this.

772:2x 2x 193

724:2x 2x 181

630:2x 3x 3x 5x 7

172:2x 2x 43

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 60565438080/(2x16)

LCM = 60565438080/32

LCM = 1892669940

Thus, we can understand that the LCM of 772,724,630,172 is 1892669940.
