Given numbers are 777,431,862,221

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

The LCM of 777,431,862,221 is 148020054.

Find LCM of 777,431,862,221 with Prime Factorization

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

431 x 777 x 1 x 2 x 221 = 148020054

Therefore, the lowest common multiple of 777,431,862,221 is 148020054.

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.

777 x 431 x 862 x 221 = 63796643274

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.

777 : 1, 3, 7, 21, 37, 111, 259, 777

431 : 1, 431

862 : 1, 2, 431, 862

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,431,862,221, is 1.

Now, the common factors can be found like this.

777:3x 7x 37

431:431

862:2x 431

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.

431 = 431

Therefore, the value for common factors is 431.

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 = 63796643274/(1x431)

LCM = 63796643274/431

LCM = 148020054

Thus, we can understand that the LCM of 777,431,862,221 is 148020054.
