Find LCM of 161,765,987,376,697 with Prime Factorization


3 161, 765, 987, 376, 697
7 161, 255, 329, 376, 697
17 23, 255, 47, 376, 697
47 23, 15, 47, 376, 41
23, 15, 1, 8, 41

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

3 x 7 x 17 x 47 x 23 x 15 x 1 x 8 x 41 = 1898711640

Therefore, the lowest common multiple of 161,765,987,376,697 is 1898711640.

LCM Formula to Find Lowest Common Multiple of 161,765,987,376,697

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 765 x 987 x 376 x 697 = 31858482607560

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

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

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

376 : 1, 2, 4, 8, 47, 94, 188, 376

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,765,987,376,697, is 1.

Now, the common factors can be found like this.

161:7x 23

765:3x 3x 5x 17

987:3x 7x 47

376:2x 2x 2x 47

697:17x 41

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

3x 7x 17x 47 = 16779

Therefore, the value for common factors is 16779.

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 = 31858482607560/(1x16779)

LCM = 31858482607560/16779

LCM = 1898711640

Thus, we can understand that the LCM of 161,765,987,376,697 is 1898711640.
