Calculate the LCM of 987,347,974,122

Given numbers are 987,347,974,122

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

The LCM of 987,347,974,122 is 20348641446.

Find LCM of 987,347,974,122 with Prime Factorization


2 987, 347, 974, 122
987, 347, 487, 61

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

2 x 987 x 347 x 487 x 61 = 20348641446

Therefore, the lowest common multiple of 987,347,974,122 is 20348641446.

LCM Formula to Find Lowest Common Multiple of 987,347,974,122

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.

987 x 347 x 974 x 122 = 40697282892

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.

987 : 1, 3, 7, 21, 47, 141, 329, 987

347 : 1, 347

974 : 1, 2, 487, 974

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,347,974,122, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

347:347

974:2x 487

122:2x 61

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 = 40697282892/(1x2)

LCM = 40697282892/2

LCM = 20348641446

Thus, we can understand that the LCM of 987,347,974,122 is 20348641446.
