Given numbers are 719,621,154,286

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

The LCM of 719,621,154,286 is 893890998.

Find LCM of 719,621,154,286 with Prime Factorization

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

2 x 11 x 719 x 621 x 7 x 13 = 893890998

Therefore, the lowest common multiple of 719,621,154,286 is 893890998.

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.

719 x 621 x 154 x 286 = 19665601956

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.

719 : 1, 719

621 : 1, 3, 9, 23, 27, 69, 207, 621

154 : 1, 2, 7, 11, 14, 22, 77, 154

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 719,621,154,286, is 1.

Now, the common factors can be found like this.

719:719

621:3x 3x 3x 23

154:2x 7x 11

286:2x 11x 13

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 19665601956/(1x22)

LCM = 19665601956/22

LCM = 893890998

Thus, we can understand that the LCM of 719,621,154,286 is 893890998.
