Calculate the LCM of 421,628,739,739

Given numbers are 421,628,739,739

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

The LCM of 421,628,739,739 is 195382732.

Find LCM of 421,628,739,739 with Prime Factorization


739 421, 628, 739, 739
421, 628, 1, 1

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

739 x 421 x 628 x 1 x 1 = 195382732

Therefore, the lowest common multiple of 421,628,739,739 is 195382732.

LCM Formula to Find Lowest Common Multiple of 421,628,739,739

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 628 x 739 x 739 = 144387838948

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

628 : 1, 2, 4, 157, 314, 628

739 : 1, 739

739 : 1, 739

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,628,739,739, is 1.

Now, the common factors can be found like this.

421:421

628:2x 2x 157

739:739

739:739

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

739 = 739

Therefore, the value for common factors is 739.

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 = 144387838948/(1x739)

LCM = 144387838948/739

LCM = 195382732

Thus, we can understand that the LCM of 421,628,739,739 is 195382732.
