Calculate the LCM of 771,777,228,648

Given numbers are 771,777,228,648

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

The LCM of 771,777,228,648 is 819523656.

Find LCM of 771,777,228,648 with Prime Factorization


2 771, 777, 228, 648
2 771, 777, 114, 324
3 771, 777, 57, 162
257, 259, 19, 54

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

2 x 2 x 3 x 257 x 259 x 19 x 54 = 819523656

Therefore, the lowest common multiple of 771,777,228,648 is 819523656.

LCM Formula to Find Lowest Common Multiple of 771,777,228,648

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.

771 x 777 x 228 x 648 = 88508554848

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.

771 : 1, 3, 257, 771

777 : 1, 3, 7, 21, 37, 111, 259, 777

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,777,228,648, is 3.

Now, the common factors can be found like this.

771:3x 257

777:3x 7x 37

228:2x 2x 3x 19

648:2x 2x 2x 3x 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 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 88508554848/(3x36)

LCM = 88508554848/108

LCM = 819523656

Thus, we can understand that the LCM of 771,777,228,648 is 819523656.
