Calculate the LCM of 123,705,769,902,745

Given numbers are 123,705,769,902,745

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

The LCM of 123,705,769,902,745 is 72863203710.

Find LCM of 123,705,769,902,745 with Prime Factorization


3 123, 705, 769, 902, 745
5 41, 235, 769, 902, 745
41 41, 47, 769, 902, 149
1, 47, 769, 22, 149

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

3 x 5 x 41 x 1 x 47 x 769 x 22 x 149 = 72863203710

Therefore, the lowest common multiple of 123,705,769,902,745 is 72863203710.

LCM Formula to Find Lowest Common Multiple of 123,705,769,902,745

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.

123 x 705 x 769 x 902 x 745 = 44810870281650

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.

123 : 1, 3, 41, 123

705 : 1, 3, 5, 15, 47, 141, 235, 705

769 : 1, 769

902 : 1, 2, 11, 22, 41, 82, 451, 902

745 : 1, 5, 149, 745

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,705,769,902,745, is 1.

Now, the common factors can be found like this.

123:3x 41

705:3x 5x 47

769:769

902:2x 11x 41

745:5x 149

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

3x 5x 41 = 615

Therefore, the value for common factors is 615.

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 = 44810870281650/(1x615)

LCM = 44810870281650/615

LCM = 72863203710

Thus, we can understand that the LCM of 123,705,769,902,745 is 72863203710.
