Calculate the LCM of 644,489,758,209,723

Given numbers are 644,489,758,209,723

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

The LCM of 644,489,758,209,723 is 6011699517516.

Find LCM of 644,489,758,209,723 with Prime Factorization


2 644, 489, 758, 209, 723
3 322, 489, 379, 209, 723
322, 163, 379, 209, 241

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

2 x 3 x 322 x 163 x 379 x 209 x 241 = 6011699517516

Therefore, the lowest common multiple of 644,489,758,209,723 is 6011699517516.

LCM Formula to Find Lowest Common Multiple of 644,489,758,209,723

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.

644 x 489 x 758 x 209 x 723 = 36070197105096

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

489 : 1, 3, 163, 489

758 : 1, 2, 379, 758

209 : 1, 11, 19, 209

723 : 1, 3, 241, 723

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,489,758,209,723, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

489:3x 163

758:2x 379

209:11x 19

723:3x 241

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 36070197105096/(1x6)

LCM = 36070197105096/6

LCM = 6011699517516

Thus, we can understand that the LCM of 644,489,758,209,723 is 6011699517516.
