Given numbers are 971,982,247,638

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

The LCM of 971,982,247,638 is 75130858946.

Find LCM of 971,982,247,638 with Prime Factorization

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

2 x 971 x 491 x 247 x 319 = 75130858946

Therefore, the lowest common multiple of 971,982,247,638 is 75130858946.

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.

971 x 982 x 247 x 638 = 150261717892

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.

971 : 1, 971

982 : 1, 2, 491, 982

247 : 1, 13, 19, 247

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,982,247,638, is 1.

Now, the common factors can be found like this.

971:971

982:2x 491

247:13x 19

638:2x 11x 29

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

2 = 2

Therefore, the value for common factors is 2.

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 = 150261717892/(1x2)

LCM = 150261717892/2

LCM = 75130858946

Thus, we can understand that the LCM of 971,982,247,638 is 75130858946.
