Find LCM of 690,161,119,918 with Prime Factorization


2 690, 161, 119, 918
3 345, 161, 119, 459
7 115, 161, 119, 153
17 115, 23, 17, 153
23 115, 23, 1, 9
5, 1, 1, 9

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

2 x 3 x 7 x 17 x 23 x 5 x 1 x 1 x 9 = 738990

Therefore, the lowest common multiple of 690,161,119,918 is 738990.

LCM Formula to Find Lowest Common Multiple of 690,161,119,918

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.

690 x 161 x 119 x 918 = 12135693780

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

161 : 1, 7, 23, 161

119 : 1, 7, 17, 119

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,161,119,918, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

161:7x 23

119:7x 17

918:2x 3x 3x 3x 17

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

2x 3x 7x 17x 23 = 16422

Therefore, the value for common factors is 16422.

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 = 12135693780/(1x16422)

LCM = 12135693780/16422

LCM = 738990

Thus, we can understand that the LCM of 690,161,119,918 is 738990.
