Given numbers are 730,186,868,821

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

The LCM of 730,186,868,821 is 780327660.

Find LCM of 730,186,868,821 with Prime Factorization

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

2 x 31 x 365 x 3 x 14 x 821 = 780327660

Therefore, the lowest common multiple of 730,186,868,821 is 780327660.

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.

730 x 186 x 868 x 821 = 96760629840

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.

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

186 : 1, 2, 3, 6, 31, 62, 93, 186

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,186,868,821, is 1.

Now, the common factors can be found like this.

730:2x 5x 73

186:2x 3x 31

868:2x 2x 7x 31

821:821

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 31 = 124

Therefore, the value for common factors is 124.

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 = 96760629840/(1x124)

LCM = 96760629840/124

LCM = 780327660

Thus, we can understand that the LCM of 730,186,868,821 is 780327660.
