Given numbers are 551,163,740,978

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

The LCM of 551,163,740,978 is 199384860.

Find LCM of 551,163,740,978 with Prime Factorization

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

2 x 163 x 551 x 1 x 370 x 3 = 199384860

Therefore, the lowest common multiple of 551,163,740,978 is 199384860.

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.

551 x 163 x 740 x 978 = 64999464360

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.

551 : 1, 19, 29, 551

163 : 1, 163

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

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 551,163,740,978, is 1.

Now, the common factors can be found like this.

551:19x 29

163:163

740:2x 2x 5x 37

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 163 = 326

Therefore, the value for common factors is 326.

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 = 64999464360/(1x326)

LCM = 64999464360/326

LCM = 199384860

Thus, we can understand that the LCM of 551,163,740,978 is 199384860.
