Given numbers are 647,146,803,947

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

The LCM of 647,146,803,947 is 984010654.

Find LCM of 647,146,803,947 with Prime Factorization

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

73 x 647 x 2 x 11 x 947 = 984010654

Therefore, the lowest common multiple of 647,146,803,947 is 984010654.

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.

647 x 146 x 803 x 947 = 71832777742

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.

647 : 1, 647

146 : 1, 2, 73, 146

803 : 1, 11, 73, 803

947 : 1, 947

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,146,803,947, is 1.

Now, the common factors can be found like this.

647:647

146:2x 73

803:11x 73

947:947

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

73 = 73

Therefore, the value for common factors is 73.

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 = 71832777742/(1x73)

LCM = 71832777742/73

LCM = 984010654

Thus, we can understand that the LCM of 647,146,803,947 is 984010654.
