Given numbers are 421,139,973

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

The LCM of 421,139,973 is 409633.

Find LCM of 421,139,973 with Prime Factorization

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

139 x 421 x 1 x 7 = 409633

Therefore, the lowest common multiple of 421,139,973 is 409633.

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.

421 x 139 x 973 = 56938987

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.

421 : 1, 421

139 : 1, 139

973 : 1, 7, 139, 973

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,139,973, is 1.

Now, the common factors can be found like this.

421:421

139:139

973:7x 139

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

139 = 139

Therefore, the value for common factors is 139.

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 = 56938987/(1x139)

LCM = 56938987/139

LCM = 409633

Thus, we can understand that the LCM of 421,139,973 is 409633.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 458, 624, 551
• LCM of 338, 457, 517
