Given numbers are 217,154,851

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

The LCM of 217,154,851 is 4062674.

Find LCM of 217,154,851 with Prime Factorization

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

7 x 31 x 22 x 851 = 4062674

Therefore, the lowest common multiple of 217,154,851 is 4062674.

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.

217 x 154 x 851 = 28438718

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.

217 : 1, 7, 31, 217

154 : 1, 2, 7, 11, 14, 22, 77, 154

851 : 1, 23, 37, 851

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,154,851, is 1.

Now, the common factors can be found like this.

217:7x 31

154:2x 7x 11

851:23x 37

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

7 = 7

Therefore, the value for common factors is 7.

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 = 28438718/(1x7)

LCM = 28438718/7

LCM = 4062674

Thus, we can understand that the LCM of 217,154,851 is 4062674.

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

• LCM of 977, 711, 155
• LCM of 835, 775, 464
