Given numbers are 247,245,721,745

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

The LCM of 247,245,721,745 is 928723705.

Find LCM of 247,245,721,745 with Prime Factorization

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

5 x 7 x 247 x 7 x 103 x 149 = 928723705

Therefore, the lowest common multiple of 247,245,721,745 is 928723705.

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.

247 x 245 x 721 x 745 = 32505329675

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.

247 : 1, 13, 19, 247

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

721 : 1, 7, 103, 721

745 : 1, 5, 149, 745

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,245,721,745, is 1.

Now, the common factors can be found like this.

247:13x 19

245:5x 7x 7

721:7x 103

745:5x 149

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

5x 7 = 35

Therefore, the value for common factors is 35.

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 = 32505329675/(1x35)

LCM = 32505329675/35

LCM = 928723705

Thus, we can understand that the LCM of 247,245,721,745 is 928723705.
