Calculate the LCM of 609,270,238,987

Given numbers are 609,270,238,987

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

The LCM of 609,270,238,987 is 43793190.

Find LCM of 609,270,238,987 with Prime Factorization


2 609, 270, 238, 987
3 609, 135, 119, 987
7 203, 45, 119, 329
29, 45, 17, 47

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

2 x 3 x 7 x 29 x 45 x 17 x 47 = 43793190

Therefore, the lowest common multiple of 609,270,238,987 is 43793190.

LCM Formula to Find Lowest Common Multiple of 609,270,238,987

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.

609 x 270 x 238 x 987 = 38625593580

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.

609 : 1, 3, 7, 21, 29, 87, 203, 609

270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

238 : 1, 2, 7, 14, 17, 34, 119, 238

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,270,238,987, is 1.

Now, the common factors can be found like this.

609:3x 7x 29

270:2x 3x 3x 3x 5

238:2x 7x 17

987:3x 7x 47

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

2x 3x 3x 7x 7 = 882

Therefore, the value for common factors is 882.

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 = 38625593580/(1x882)

LCM = 38625593580/882

LCM = 43793190

Thus, we can understand that the LCM of 609,270,238,987 is 43793190.
