Given numbers are 745,678,215,245

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

The LCM of 745,678,215,245 is 1064266770.

Find LCM of 745,678,215,245 with Prime Factorization

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

5 x 149 x 678 x 43 x 49 = 1064266770

Therefore, the lowest common multiple of 745,678,215,245 is 1064266770.

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 678 x 215 x 245 = 26606669250

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

678 : 1, 2, 3, 6, 113, 226, 339, 678

215 : 1, 5, 43, 215

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,678,215,245, is 1.

Now, the common factors can be found like this.

745:5x 149

678:2x 3x 113

215:5x 43

245:5x 7x 7

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 26606669250/(1x25)

LCM = 26606669250/25

LCM = 1064266770

Thus, we can understand that the LCM of 745,678,215,245 is 1064266770.
