Given numbers are 169,221,102,551

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

The LCM of 169,221,102,551 is 9498138.

Find LCM of 169,221,102,551 with Prime Factorization

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

13 x 17 x 13 x 1 x 6 x 551 = 9498138

Therefore, the lowest common multiple of 169,221,102,551 is 9498138.

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.

169 x 221 x 102 x 551 = 2099088498

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.

169 : 1, 13, 169

221 : 1, 13, 17, 221

102 : 1, 2, 3, 6, 17, 34, 51, 102

551 : 1, 19, 29, 551

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,221,102,551, is 1.

Now, the common factors can be found like this.

169:13x 13

221:13x 17

102:2x 3x 17

551:19x 29

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

13x 17 = 221

Therefore, the value for common factors is 221.

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 = 2099088498/(1x221)

LCM = 2099088498/221

LCM = 9498138

Thus, we can understand that the LCM of 169,221,102,551 is 9498138.
