Calculate the LCM of 490,347,669,220

Given numbers are 490,347,669,220

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

The LCM of 490,347,669,220 is 2502501540.

Find LCM of 490,347,669,220 with Prime Factorization


2 490, 347, 669, 220
5 245, 347, 669, 110
49, 347, 669, 22

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

2 x 5 x 49 x 347 x 669 x 22 = 2502501540

Therefore, the lowest common multiple of 490,347,669,220 is 2502501540.

LCM Formula to Find Lowest Common Multiple of 490,347,669,220

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.

490 x 347 x 669 x 220 = 25025015400

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.

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

347 : 1, 347

669 : 1, 3, 223, 669

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,347,669,220, is 1.

Now, the common factors can be found like this.

490:2x 5x 7x 7

347:347

669:3x 223

220:2x 2x 5x 11

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 25025015400/(1x10)

LCM = 25025015400/10

LCM = 2502501540

Thus, we can understand that the LCM of 490,347,669,220 is 2502501540.
