Given numbers are 771,638,120,739

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

The LCM of 771,638,120,739 is 7270252440.

Find LCM of 771,638,120,739 with Prime Factorization

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

2 x 3 x 257 x 319 x 20 x 739 = 7270252440

Therefore, the lowest common multiple of 771,638,120,739 is 7270252440.

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.

771 x 638 x 120 x 739 = 43621514640

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.

771 : 1, 3, 257, 771

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

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

739 : 1, 739

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,638,120,739, is 1.

Now, the common factors can be found like this.

771:3x 257

638:2x 11x 29

120:2x 2x 2x 3x 5

739:739

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 43621514640/(1x6)

LCM = 43621514640/6

LCM = 7270252440

Thus, we can understand that the LCM of 771,638,120,739 is 7270252440.
