The LCM of 702,171,211,987 is 925910622.

Find LCM of 702,171,211,987 with Prime Factorization


3 702, 171, 211, 987
3 234, 57, 211, 329
78, 19, 211, 329

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

3 x 3 x 78 x 19 x 211 x 329 = 925910622

Therefore, the lowest common multiple of 702,171,211,987 is 925910622.

LCM Formula to Find Lowest Common Multiple of 702,171,211,987

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.

702 x 171 x 211 x 987 = 24999586794

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.

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

171 : 1, 3, 9, 19, 57, 171

211 : 1, 211

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,171,211,987, is 1.

Now, the common factors can be found like this.

702:2x 3x 3x 3x 13

171:3x 3x 19

211:211

987:3x 7x 47

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 24999586794/(1x27)

LCM = 24999586794/27

LCM = 925910622

Thus, we can understand that the LCM of 702,171,211,987 is 925910622.
