Given numbers are 273,138,198,251,980

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

The LCM of 273,138,198,251,980 is 7281253980.

Find LCM of 273,138,198,251,980 with Prime Factorization

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

2 x 3 x 7 x 13 x 23 x 33 x 251 x 70 = 7281253980

Therefore, the lowest common multiple of 273,138,198,251,980 is 7281253980.

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.

273 x 138 x 198 x 251 x 980 = 1834876002960

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.

273 : 1, 3, 7, 13, 21, 39, 91, 273

138 : 1, 2, 3, 6, 23, 46, 69, 138

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

251 : 1, 251

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 273,138,198,251,980, is 1.

Now, the common factors can be found like this.

273:3x 7x 13

138:2x 3x 23

198:2x 3x 3x 11

251:251

980:2x 2x 5x 7x 7

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

2x 2x 3x 3x 7 = 252

Therefore, the value for common factors is 252.

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 = 1834876002960/(1x252)

LCM = 1834876002960/252

LCM = 7281253980

Thus, we can understand that the LCM of 273,138,198,251,980 is 7281253980.
