Calculate the LCM of 931,391,462,889

Given numbers are 931,391,462,889

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

The LCM of 931,391,462,889 is 3051224022.

Find LCM of 931,391,462,889 with Prime Factorization


7 931, 391, 462, 889
133, 391, 66, 127

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

7 x 133 x 391 x 66 x 127 = 3051224022

Therefore, the lowest common multiple of 931,391,462,889 is 3051224022.

LCM Formula to Find Lowest Common Multiple of 931,391,462,889

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.

931 x 391 x 462 x 889 = 149509977078

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.

931 : 1, 7, 19, 49, 133, 931

391 : 1, 17, 23, 391

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

889 : 1, 7, 127, 889

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,391,462,889, is 1.

Now, the common factors can be found like this.

931:7x 7x 19

391:17x 23

462:2x 3x 7x 11

889:7x 127

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 149509977078/(1x49)

LCM = 149509977078/49

LCM = 3051224022

Thus, we can understand that the LCM of 931,391,462,889 is 3051224022.
