Given numbers are 745,708,130,821

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

The LCM of 745,708,130,821 is 5629580580.

Find LCM of 745,708,130,821 with Prime Factorization

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

2 x 5 x 149 x 354 x 13 x 821 = 5629580580

Therefore, the lowest common multiple of 745,708,130,821 is 5629580580.

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.

745 x 708 x 130 x 821 = 56295805800

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.

745 : 1, 5, 149, 745

708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708

130 : 1, 2, 5, 10, 13, 26, 65, 130

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,708,130,821, is 1.

Now, the common factors can be found like this.

745:5x 149

708:2x 2x 3x 59

130:2x 5x 13

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 5 = 10

Therefore, the value for common factors is 10.

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 = 56295805800/(1x10)

LCM = 56295805800/10

LCM = 5629580580

Thus, we can understand that the LCM of 745,708,130,821 is 5629580580.
