Given numbers are 511,438,419,947

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

The LCM of 511,438,419,947 is 1216567338.

Find LCM of 511,438,419,947 with Prime Factorization

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

73 x 7 x 6 x 419 x 947 = 1216567338

Therefore, the lowest common multiple of 511,438,419,947 is 1216567338.

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.

511 x 438 x 419 x 947 = 88809415674

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.

511 : 1, 7, 73, 511

438 : 1, 2, 3, 6, 73, 146, 219, 438

419 : 1, 419

947 : 1, 947

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 511,438,419,947, is 1.

Now, the common factors can be found like this.

511:7x 73

438:2x 3x 73

419:419

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 = 88809415674/(1x73)

LCM = 88809415674/73

LCM = 1216567338

Thus, we can understand that the LCM of 511,438,419,947 is 1216567338.
