Calculate the LCM of 421,763,546,390,866

Given numbers are 421,763,546,390,866

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

The LCM of 421,763,546,390,866 is 54244928010.

Find LCM of 421,763,546,390,866 with Prime Factorization


2 421, 763, 546, 390, 866
3 421, 763, 273, 195, 433
7 421, 763, 91, 65, 433
13 421, 109, 13, 65, 433
421, 109, 1, 5, 433

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

2 x 3 x 7 x 13 x 421 x 109 x 1 x 5 x 433 = 54244928010

Therefore, the lowest common multiple of 421,763,546,390,866 is 54244928010.

LCM Formula to Find Lowest Common Multiple of 421,763,546,390,866

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.

421 x 763 x 546 x 390 x 866 = 59235461386920

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.

421 : 1, 421

763 : 1, 7, 109, 763

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

866 : 1, 2, 433, 866

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,763,546,390,866, is 1.

Now, the common factors can be found like this.

421:421

763:7x 109

546:2x 3x 7x 13

390:2x 3x 5x 13

866:2x 433

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 7x 13 = 1092

Therefore, the value for common factors is 1092.

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 = 59235461386920/(1x1092)

LCM = 59235461386920/1092

LCM = 54244928010

Thus, we can understand that the LCM of 421,763,546,390,866 is 54244928010.
