Given numbers are 690,247,748,121,439

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

The LCM of 690,247,748,121,439 is 307804419780.

Find LCM of 690,247,748,121,439 with Prime Factorization

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

2 x 11 x 345 x 247 x 34 x 11 x 439 = 307804419780

Therefore, the lowest common multiple of 690,247,748,121,439 is 307804419780.

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.

690 x 247 x 748 x 121 x 439 = 6771697235160

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

247 : 1, 13, 19, 247

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

121 : 1, 11, 121

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,247,748,121,439, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

247:13x 19

748:2x 2x 11x 17

121:11x 11

439:439

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 6771697235160/(1x22)

LCM = 6771697235160/22

LCM = 307804419780

Thus, we can understand that the LCM of 690,247,748,121,439 is 307804419780.
