Calculate the LCM of 749,789,169,434,771

Given numbers are 749,789,169,434,771

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

The LCM of 749,789,169,434,771 is 1591366965006.

Find LCM of 749,789,169,434,771 with Prime Factorization


3 749, 789, 169, 434, 771
7 749, 263, 169, 434, 257
107, 263, 169, 62, 257

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

3 x 7 x 107 x 263 x 169 x 62 x 257 = 1591366965006

Therefore, the lowest common multiple of 749,789,169,434,771 is 1591366965006.

LCM Formula to Find Lowest Common Multiple of 749,789,169,434,771

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.

749 x 789 x 169 x 434 x 771 = 33418706265126

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.

749 : 1, 7, 107, 749

789 : 1, 3, 263, 789

169 : 1, 13, 169

434 : 1, 2, 7, 14, 31, 62, 217, 434

771 : 1, 3, 257, 771

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,789,169,434,771, is 1.

Now, the common factors can be found like this.

749:7x 107

789:3x 263

169:13x 13

434:2x 7x 31

771:3x 257

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 33418706265126/(1x21)

LCM = 33418706265126/21

LCM = 1591366965006

Thus, we can understand that the LCM of 749,789,169,434,771 is 1591366965006.
