Given numbers are 987,118,172,118,661

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

The LCM of 987,118,172,118,661 is 6620626236.

Find LCM of 987,118,172,118,661 with Prime Factorization

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

2 x 59 x 987 x 1 x 86 x 1 x 661 = 6620626236

Therefore, the lowest common multiple of 987,118,172,118,661 is 6620626236.

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 118 x 172 x 118 x 661 = 1562467791696

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

118 : 1, 2, 59, 118

172 : 1, 2, 4, 43, 86, 172

118 : 1, 2, 59, 118

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,118,172,118,661, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

118:2x 59

172:2x 2x 43

118:2x 59

661:661

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 59 = 236

Therefore, the value for common factors is 236.

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 = 1562467791696/(1x236)

LCM = 1562467791696/236

LCM = 6620626236

Thus, we can understand that the LCM of 987,118,172,118,661 is 6620626236.
