Given numbers are 653,170,434,321

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

The LCM of 653,170,434,321 is 7732623570.

Find LCM of 653,170,434,321 with Prime Factorization

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

2 x 653 x 85 x 217 x 321 = 7732623570

Therefore, the lowest common multiple of 653,170,434,321 is 7732623570.

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.

653 x 170 x 434 x 321 = 15465247140

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.

653 : 1, 653

170 : 1, 2, 5, 10, 17, 34, 85, 170

434 : 1, 2, 7, 14, 31, 62, 217, 434

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 653,170,434,321, is 1.

Now, the common factors can be found like this.

653:653

170:2x 5x 17

434:2x 7x 31

321:3x 107

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

2 = 2

Therefore, the value for common factors is 2.

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 = 15465247140/(1x2)

LCM = 15465247140/2

LCM = 7732623570

Thus, we can understand that the LCM of 653,170,434,321 is 7732623570.
