Calculate the LCM of 723,648,220,202

Given numbers are 723,648,220,202

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

The LCM of 723,648,220,202 is 867513240.

Find LCM of 723,648,220,202 with Prime Factorization


2 723, 648, 220, 202
2 723, 324, 110, 101
3 723, 162, 55, 101
241, 54, 55, 101

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

2 x 2 x 3 x 241 x 54 x 55 x 101 = 867513240

Therefore, the lowest common multiple of 723,648,220,202 is 867513240.

LCM Formula to Find Lowest Common Multiple of 723,648,220,202

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.

723 x 648 x 220 x 202 = 20820317760

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.

723 : 1, 3, 241, 723

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

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

202 : 1, 2, 101, 202

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,648,220,202, is 1.

Now, the common factors can be found like this.

723:3x 241

648:2x 2x 2x 3x 3x 3x 3

220:2x 2x 5x 11

202:2x 101

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 3 = 24

Therefore, the value for common factors is 24.

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 = 20820317760/(1x24)

LCM = 20820317760/24

LCM = 867513240

Thus, we can understand that the LCM of 723,648,220,202 is 867513240.
