Given numbers are 868,545,209,437

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

The LCM of 868,545,209,437 is 2273999420.

Find LCM of 868,545,209,437 with Prime Factorization

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

19 x 868 x 545 x 11 x 23 = 2273999420

Therefore, the lowest common multiple of 868,545,209,437 is 2273999420.

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.

868 x 545 x 209 x 437 = 43205988980

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.

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

545 : 1, 5, 109, 545

209 : 1, 11, 19, 209

437 : 1, 19, 23, 437

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,545,209,437, is 1.

Now, the common factors can be found like this.

868:2x 2x 7x 31

545:5x 109

209:11x 19

437:19x 23

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

19 = 19

Therefore, the value for common factors is 19.

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 = 43205988980/(1x19)

LCM = 43205988980/19

LCM = 2273999420

Thus, we can understand that the LCM of 868,545,209,437 is 2273999420.
