Given numbers are 678,989,978,201

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

The LCM of 678,989,978,201 is 7322989182.

Find LCM of 678,989,978,201 with Prime Factorization

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

2 x 3 x 113 x 989 x 163 x 67 = 7322989182

Therefore, the lowest common multiple of 678,989,978,201 is 7322989182.

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.

678 x 989 x 978 x 201 = 131813805276

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

989 : 1, 23, 43, 989

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

201 : 1, 3, 67, 201

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,989,978,201, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

989:23x 43

978:2x 3x 163

201:3x 67

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 131813805276/(1x18)

LCM = 131813805276/18

LCM = 7322989182

Thus, we can understand that the LCM of 678,989,978,201 is 7322989182.
