Given numbers are 174,118,421

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

The LCM of 174,118,421 is 4321986.

Find LCM of 174,118,421 with Prime Factorization

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

2 x 87 x 59 x 421 = 4321986

Therefore, the lowest common multiple of 174,118,421 is 4321986.

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.

174 x 118 x 421 = 8643972

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.

174 : 1, 2, 3, 6, 29, 58, 87, 174

118 : 1, 2, 59, 118

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 174,118,421, is 1.

Now, the common factors can be found like this.

174:2x 3x 29

118:2x 59

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.

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 = 8643972/(1x2)

LCM = 8643972/2

LCM = 4321986

Thus, we can understand that the LCM of 174,118,421 is 4321986.

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

• LCM of 270, 343, 703
• LCM of 929, 346, 161
