Calculate the LCM of 661,941,924,440

Given numbers are 661,941,924,440

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

The LCM of 661,941,924,440 is 5747289240.

Find LCM of 661,941,924,440 with Prime Factorization


2 661, 941, 924, 440
2 661, 941, 462, 220
11 661, 941, 231, 110
661, 941, 21, 10

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

2 x 2 x 11 x 661 x 941 x 21 x 10 = 5747289240

Therefore, the lowest common multiple of 661,941,924,440 is 5747289240.

LCM Formula to Find Lowest Common Multiple of 661,941,924,440

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.

661 x 941 x 924 x 440 = 252880726560

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.

661 : 1, 661

941 : 1, 941

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,941,924,440, is 1.

Now, the common factors can be found like this.

661:661

941:941

924:2x 2x 3x 7x 11

440:2x 2x 2x 5x 11

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

2x 2x 11 = 44

Therefore, the value for common factors is 44.

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 = 252880726560/(1x44)

LCM = 252880726560/44

LCM = 5747289240

Thus, we can understand that the LCM of 661,941,924,440 is 5747289240.
