Calculate the LCM of 691,959,378

Given numbers are 691,959,378

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

The LCM of 691,959,378 is 35784126.

Find LCM of 691,959,378 with Prime Factorization


7 691, 959, 378
691, 137, 54

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

7 x 691 x 137 x 54 = 35784126

Therefore, the lowest common multiple of 691,959,378 is 35784126.

LCM Formula to Find Lowest Common Multiple of 691,959,378

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.

691 x 959 x 378 = 250488882

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.

691 : 1, 691

959 : 1, 7, 137, 959

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,959,378, is 1.

Now, the common factors can be found like this.

691:691

959:7x 137

378:2x 3x 3x 3x 7

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

7 = 7

Therefore, the value for common factors is 7.

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 = 250488882/(1x7)

LCM = 250488882/7

LCM = 35784126

Thus, we can understand that the LCM of 691,959,378 is 35784126.
