Calculate the LCM of 649,288,290,985

Given numbers are 649,288,290,985

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

The LCM of 649,288,290,985 is 5339141280.

Find LCM of 649,288,290,985 with Prime Factorization


2 649, 288, 290, 985
5 649, 144, 145, 985
649, 144, 29, 197

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

2 x 5 x 649 x 144 x 29 x 197 = 5339141280

Therefore, the lowest common multiple of 649,288,290,985 is 5339141280.

LCM Formula to Find Lowest Common Multiple of 649,288,290,985

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.

649 x 288 x 290 x 985 = 53391412800

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.

649 : 1, 11, 59, 649

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

290 : 1, 2, 5, 10, 29, 58, 145, 290

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,288,290,985, is 1.

Now, the common factors can be found like this.

649:11x 59

288:2x 2x 2x 2x 2x 3x 3

290:2x 5x 29

985:5x 197

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 = 53391412800/(1x10)

LCM = 53391412800/10

LCM = 5339141280

Thus, we can understand that the LCM of 649,288,290,985 is 5339141280.
