Calculate the LCM of 693,190,421,715

Given numbers are 693,190,421,715

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

The LCM of 693,190,421,715 is 720629910.

Find LCM of 693,190,421,715 with Prime Factorization


5 693, 190, 421, 715
11 693, 38, 421, 143
63, 38, 421, 13

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

5 x 11 x 63 x 38 x 421 x 13 = 720629910

Therefore, the lowest common multiple of 693,190,421,715 is 720629910.

LCM Formula to Find Lowest Common Multiple of 693,190,421,715

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.

693 x 190 x 421 x 715 = 39634645050

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.

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

190 : 1, 2, 5, 10, 19, 38, 95, 190

421 : 1, 421

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,190,421,715, is 1.

Now, the common factors can be found like this.

693:3x 3x 7x 11

190:2x 5x 19

421:421

715:5x 11x 13

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

5x 11 = 55

Therefore, the value for common factors is 55.

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 = 39634645050/(1x55)

LCM = 39634645050/55

LCM = 720629910

Thus, we can understand that the LCM of 693,190,421,715 is 720629910.
