Given numbers are 421,533,769,769

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

The LCM of 421,533,769,769 is 172558217.

Find LCM of 421,533,769,769 with Prime Factorization

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

769 x 421 x 533 x 1 x 1 = 172558217

Therefore, the lowest common multiple of 421,533,769,769 is 172558217.

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.

421 x 533 x 769 x 769 = 132697268873

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.

421 : 1, 421

533 : 1, 13, 41, 533

769 : 1, 769

769 : 1, 769

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,533,769,769, is 1.

Now, the common factors can be found like this.

421:421

533:13x 41

769:769

769:769

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

769 = 769

Therefore, the value for common factors is 769.

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 = 132697268873/(1x769)

LCM = 132697268873/769

LCM = 172558217

Thus, we can understand that the LCM of 421,533,769,769 is 172558217.
