Given numbers are 278,471,973,221

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

The LCM of 278,471,973,221 is 202561086.

Find LCM of 278,471,973,221 with Prime Factorization

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

139 x 2 x 471 x 7 x 221 = 202561086

Therefore, the lowest common multiple of 278,471,973,221 is 202561086.

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.

278 x 471 x 973 x 221 = 28155990954

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.

278 : 1, 2, 139, 278

471 : 1, 3, 157, 471

973 : 1, 7, 139, 973

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,471,973,221, is 1.

Now, the common factors can be found like this.

278:2x 139

471:3x 157

973:7x 139

221:13x 17

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

139 = 139

Therefore, the value for common factors is 139.

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 = 28155990954/(1x139)

LCM = 28155990954/139

LCM = 202561086

Thus, we can understand that the LCM of 278,471,973,221 is 202561086.
