The LCM of 869,649,248,608 is 966355808.

Find LCM of 869,649,248,608 with Prime Factorization


2 869, 649, 248, 608
2 869, 649, 124, 304
2 869, 649, 62, 152
11 869, 649, 31, 76
79, 59, 31, 76

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

2 x 2 x 2 x 11 x 79 x 59 x 31 x 76 = 966355808

Therefore, the lowest common multiple of 869,649,248,608 is 966355808.

LCM Formula to Find Lowest Common Multiple of 869,649,248,608

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.

869 x 649 x 248 x 608 = 85039311104

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.

869 : 1, 11, 79, 869

649 : 1, 11, 59, 649

248 : 1, 2, 4, 8, 31, 62, 124, 248

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,649,248,608, is 1.

Now, the common factors can be found like this.

869:11x 79

649:11x 59

248:2x 2x 2x 31

608:2x 2x 2x 2x 2x 19

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 2x 11 = 88

Therefore, the value for common factors is 88.

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 = 85039311104/(1x88)

LCM = 85039311104/88

LCM = 966355808

Thus, we can understand that the LCM of 869,649,248,608 is 966355808.
