Calculate the LCM of 253,665,860,978

Given numbers are 253,665,860,978

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

The LCM of 253,665,860,978 is 14150750460.

Find LCM of 253,665,860,978 with Prime Factorization


2 253, 665, 860, 978
5 253, 665, 430, 489
253, 133, 86, 489

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

2 x 5 x 253 x 133 x 86 x 489 = 14150750460

Therefore, the lowest common multiple of 253,665,860,978 is 14150750460.

LCM Formula to Find Lowest Common Multiple of 253,665,860,978

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.

253 x 665 x 860 x 978 = 141507504600

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.

253 : 1, 11, 23, 253

665 : 1, 5, 7, 19, 35, 95, 133, 665

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,665,860,978, is 1.

Now, the common factors can be found like this.

253:11x 23

665:5x 7x 19

860:2x 2x 5x 43

978:2x 3x 163

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 141507504600/(1x10)

LCM = 141507504600/10

LCM = 14150750460

Thus, we can understand that the LCM of 253,665,860,978 is 14150750460.
