Given numbers are 978,716,202,689

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

The LCM of 978,716,202,689 is 24364779036.

Find LCM of 978,716,202,689 with Prime Factorization

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

2 x 489 x 358 x 101 x 689 = 24364779036

Therefore, the lowest common multiple of 978,716,202,689 is 24364779036.

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.

978 x 716 x 202 x 689 = 97459116144

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.

978 : 1, 2, 3, 6, 163, 326, 489, 978

716 : 1, 2, 4, 179, 358, 716

202 : 1, 2, 101, 202

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,716,202,689, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

716:2x 2x 179

202:2x 101

689:13x 53

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 97459116144/(1x4)

LCM = 97459116144/4

LCM = 24364779036

Thus, we can understand that the LCM of 978,716,202,689 is 24364779036.
