Given numbers are 690,655,244,621,234

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

The LCM of 690,655,244,621,234 is 1290226860.

Find LCM of 690,655,244,621,234 with Prime Factorization

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

2 x 3 x 3 x 5 x 23 x 1 x 131 x 122 x 3 x 13 = 1290226860

Therefore, the lowest common multiple of 690,655,244,621,234 is 1290226860.

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 655 x 244 x 621 x 234 = 16024617601200

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

655 : 1, 5, 131, 655

244 : 1, 2, 4, 61, 122, 244

621 : 1, 3, 9, 23, 27, 69, 207, 621

234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,655,244,621,234, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

655:5x 131

244:2x 2x 61

621:3x 3x 3x 23

234:2x 3x 3x 13

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

2x 2x 3x 3x 3x 5x 23 = 12420

Therefore, the value for common factors is 12420.

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 = 16024617601200/(1x12420)

LCM = 16024617601200/12420

LCM = 1290226860

Thus, we can understand that the LCM of 690,655,244,621,234 is 1290226860.
