Calculate the LCM of 471,253,978,432

Given numbers are 471,253,978,432

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

The LCM of 471,253,978,432 is 2796993936.

Find LCM of 471,253,978,432 with Prime Factorization


2 471, 253, 978, 432
3 471, 253, 489, 216
157, 253, 163, 72

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

2 x 3 x 157 x 253 x 163 x 72 = 2796993936

Therefore, the lowest common multiple of 471,253,978,432 is 2796993936.

LCM Formula to Find Lowest Common Multiple of 471,253,978,432

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.

471 x 253 x 978 x 432 = 50345890848

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.

471 : 1, 3, 157, 471

253 : 1, 11, 23, 253

978 : 1, 2, 3, 6, 163, 326, 489, 978

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,253,978,432, is 1.

Now, the common factors can be found like this.

471:3x 157

253:11x 23

978:2x 3x 163

432:2x 2x 2x 2x 3x 3x 3

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 50345890848/(1x18)

LCM = 50345890848/18

LCM = 2796993936

Thus, we can understand that the LCM of 471,253,978,432 is 2796993936.
