Calculate the LCM of 123,464,644,697

Given numbers are 123,464,644,697

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

The LCM of 123,464,644,697 is 156206064.

Find LCM of 123,464,644,697 with Prime Factorization


2 123, 464, 644, 697
2 123, 232, 322, 697
41 123, 116, 161, 697
3, 116, 161, 17

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

2 x 2 x 41 x 3 x 116 x 161 x 17 = 156206064

Therefore, the lowest common multiple of 123,464,644,697 is 156206064.

LCM Formula to Find Lowest Common Multiple of 123,464,644,697

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.

123 x 464 x 644 x 697 = 25617794496

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.

123 : 1, 3, 41, 123

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

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

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,464,644,697, is 1.

Now, the common factors can be found like this.

123:3x 41

464:2x 2x 2x 2x 29

644:2x 2x 7x 23

697:17x 41

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 41 = 164

Therefore, the value for common factors is 164.

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 = 25617794496/(1x164)

LCM = 25617794496/164

LCM = 156206064

Thus, we can understand that the LCM of 123,464,644,697 is 156206064.
