Calculate the LCM of 606,661,509,421,770

Given numbers are 606,661,509,421,770

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

The LCM of 606,661,509,421,770 is 33047201715990.

Find LCM of 606,661,509,421,770 with Prime Factorization


2 606, 661, 509, 421, 770
303, 661, 509, 421, 385

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

2 x 303 x 661 x 509 x 421 x 385 = 33047201715990

Therefore, the lowest common multiple of 606,661,509,421,770 is 33047201715990.

LCM Formula to Find Lowest Common Multiple of 606,661,509,421,770

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.

606 x 661 x 509 x 421 x 770 = 66094403431980

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.

606 : 1, 2, 3, 6, 101, 202, 303, 606

661 : 1, 661

509 : 1, 509

421 : 1, 421

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 606,661,509,421,770, is 1.

Now, the common factors can be found like this.

606:2x 3x 101

661:661

509:509

421:421

770:2x 5x 7x 11

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 = 66094403431980/(1x2)

LCM = 66094403431980/2

LCM = 33047201715990

Thus, we can understand that the LCM of 606,661,509,421,770 is 33047201715990.
