Calculate the LCM of 691,902,892,974

Given numbers are 691,902,892,974

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

The LCM of 691,902,892,974 is 135378096964.

Find LCM of 691,902,892,974 with Prime Factorization


2 691, 902, 892, 974
691, 451, 446, 487

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

2 x 691 x 451 x 446 x 487 = 135378096964

Therefore, the lowest common multiple of 691,902,892,974 is 135378096964.

LCM Formula to Find Lowest Common Multiple of 691,902,892,974

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.

691 x 902 x 892 x 974 = 541512387856

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.

691 : 1, 691

902 : 1, 2, 11, 22, 41, 82, 451, 902

892 : 1, 2, 4, 223, 446, 892

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,902,892,974, is 1.

Now, the common factors can be found like this.

691:691

902:2x 11x 41

892:2x 2x 223

974:2x 487

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 541512387856/(1x4)

LCM = 541512387856/4

LCM = 135378096964

Thus, we can understand that the LCM of 691,902,892,974 is 135378096964.
