Given numbers are 921,974,141,778

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

The LCM of 921,974,141,778 is 16400838282.

Find LCM of 921,974,141,778 with Prime Factorization

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

2 x 3 x 307 x 487 x 47 x 389 = 16400838282

Therefore, the lowest common multiple of 921,974,141,778 is 16400838282.

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.

921 x 974 x 141 x 778 = 98405029692

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.

921 : 1, 3, 307, 921

974 : 1, 2, 487, 974

141 : 1, 3, 47, 141

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,974,141,778, is 1.

Now, the common factors can be found like this.

921:3x 307

974:2x 487

141:3x 47

778:2x 389

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 98405029692/(1x6)

LCM = 98405029692/6

LCM = 16400838282

Thus, we can understand that the LCM of 921,974,141,778 is 16400838282.
