Given numbers are 161,782,118,247

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

The LCM of 161,782,118,247 is 79772602.

Find LCM of 161,782,118,247 with Prime Factorization

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

2 x 23 x 7 x 17 x 59 x 247 = 79772602

Therefore, the lowest common multiple of 161,782,118,247 is 79772602.

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.

161 x 782 x 118 x 247 = 3669539692

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.

161 : 1, 7, 23, 161

782 : 1, 2, 17, 23, 34, 46, 391, 782

118 : 1, 2, 59, 118

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,782,118,247, is 1.

Now, the common factors can be found like this.

161:7x 23

782:2x 17x 23

118:2x 59

247:13x 19

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 3669539692/(1x46)

LCM = 3669539692/46

LCM = 79772602

Thus, we can understand that the LCM of 161,782,118,247 is 79772602.
