Given numbers are 203,980,421,421

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

The LCM of 203,980,421,421 is 11964820.

Find LCM of 203,980,421,421 with Prime Factorization

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

7 x 421 x 29 x 140 x 1 x 1 = 11964820

Therefore, the lowest common multiple of 203,980,421,421 is 11964820.

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.

203 x 980 x 421 x 421 = 35260324540

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.

203 : 1, 7, 29, 203

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

421 : 1, 421

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,980,421,421, is 1.

Now, the common factors can be found like this.

203:7x 29

980:2x 2x 5x 7x 7

421:421

421:421

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

7x 421 = 2947

Therefore, the value for common factors is 2947.

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 = 35260324540/(1x2947)

LCM = 35260324540/2947

LCM = 11964820

Thus, we can understand that the LCM of 203,980,421,421 is 11964820.
