Given numbers are 245,691,728,70

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

The LCM of 245,691,728,70 is 17606680.

Find LCM of 245,691,728,70 with Prime Factorization

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

2 x 5 x 7 x 1 x 691 x 52 x 7 = 17606680

Therefore, the lowest common multiple of 245,691,728,70 is 17606680.

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.

245 x 691 x 728 x 70 = 8627273200

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.

245 : 1, 5, 7, 35, 49, 245

691 : 1, 691

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

70 : 1, 2, 5, 7, 10, 14, 35, 70

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 245,691,728,70, is 1.

Now, the common factors can be found like this.

245:5x 7x 7

691:691

728:2x 2x 2x 7x 13

70:2x 5x 7

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

2x 5x 7x 7 = 490

Therefore, the value for common factors is 490.

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 = 8627273200/(1x490)

LCM = 8627273200/490

LCM = 17606680

Thus, we can understand that the LCM of 245,691,728,70 is 17606680.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 707, 219, 499, 67
