Calculate the LCM of 850,136,688,542

Given numbers are 850,136,688,542

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

The LCM of 850,136,688,542 is 79240400.

Find LCM of 850,136,688,542 with Prime Factorization


2 850, 136, 688, 542
2 425, 68, 344, 271
2 425, 34, 172, 271
17 425, 17, 86, 271
25, 1, 86, 271

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

2 x 2 x 2 x 17 x 25 x 1 x 86 x 271 = 79240400

Therefore, the lowest common multiple of 850,136,688,542 is 79240400.

LCM Formula to Find Lowest Common Multiple of 850,136,688,542

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.

850 x 136 x 688 x 542 = 43106777600

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.

850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850

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

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

542 : 1, 2, 271, 542

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 850,136,688,542, is 2.

Now, the common factors can be found like this.

850:2x 5x 5x 17

136:2x 2x 2x 17

688:2x 2x 2x 2x 43

542:2x 271

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 2x 17 = 272

Therefore, the value for common factors is 272.

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 = 43106777600/(2x272)

LCM = 43106777600/544

LCM = 79240400

Thus, we can understand that the LCM of 850,136,688,542 is 79240400.
