Given numbers are 220,434,421,769

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

The LCM of 220,434,421,769 is 15455777260.

Find LCM of 220,434,421,769 with Prime Factorization

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

2 x 110 x 217 x 421 x 769 = 15455777260

Therefore, the lowest common multiple of 220,434,421,769 is 15455777260.

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.

220 x 434 x 421 x 769 = 30911554520

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.

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

434 : 1, 2, 7, 14, 31, 62, 217, 434

421 : 1, 421

769 : 1, 769

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,434,421,769, is 1.

Now, the common factors can be found like this.

220:2x 2x 5x 11

434:2x 7x 31

421:421

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 30911554520/(1x2)

LCM = 30911554520/2

LCM = 15455777260

Thus, we can understand that the LCM of 220,434,421,769 is 15455777260.
