Calculate the LCM of 221,136,280,761

Given numbers are 221,136,280,761

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

The LCM of 221,136,280,761 is 47090680.

Find LCM of 221,136,280,761 with Prime Factorization


2 221, 136, 280, 761
2 221, 68, 140, 761
2 221, 34, 70, 761
17 221, 17, 35, 761
13, 1, 35, 761

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

2 x 2 x 2 x 17 x 13 x 1 x 35 x 761 = 47090680

Therefore, the lowest common multiple of 221,136,280,761 is 47090680.

LCM Formula to Find Lowest Common Multiple of 221,136,280,761

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.

221 x 136 x 280 x 761 = 6404332480

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.

221 : 1, 13, 17, 221

136 : 1, 2, 4, 8, 17, 34, 68, 136

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

761 : 1, 761

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,136,280,761, is 1.

Now, the common factors can be found like this.

221:13x 17

136:2x 2x 2x 17

280:2x 2x 2x 5x 7

761:761

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

2x 2x 2x 17 = 136

Therefore, the value for common factors is 136.

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 = 6404332480/(1x136)

LCM = 6404332480/136

LCM = 47090680

Thus, we can understand that the LCM of 221,136,280,761 is 47090680.
