Given numbers are 970,186,720,691

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

The LCM of 970,186,720,691 is 1496042640.

Find LCM of 970,186,720,691 with Prime Factorization

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

2 x 3 x 5 x 97 x 31 x 24 x 691 = 1496042640

Therefore, the lowest common multiple of 970,186,720,691 is 1496042640.

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.

970 x 186 x 720 x 691 = 89762558400

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.

970 : 1, 2, 5, 10, 97, 194, 485, 970

186 : 1, 2, 3, 6, 31, 62, 93, 186

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 970,186,720,691, is 1.

Now, the common factors can be found like this.

970:2x 5x 97

186:2x 3x 31

720:2x 2x 2x 2x 3x 3x 5

691:691

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 3x 5 = 60

Therefore, the value for common factors is 60.

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 = 89762558400/(1x60)

LCM = 89762558400/60

LCM = 1496042640

Thus, we can understand that the LCM of 970,186,720,691 is 1496042640.
