Find LCM of 161,440,889,456,847 with Prime Factorization


2 161, 440, 889, 456, 847
2 161, 220, 889, 228, 847
2 161, 110, 889, 114, 847
7 161, 55, 889, 57, 847
11 23, 55, 127, 57, 121
23, 5, 127, 57, 11

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

2 x 2 x 2 x 7 x 11 x 23 x 5 x 127 x 57 x 11 = 5640918360

Therefore, the lowest common multiple of 161,440,889,456,847 is 5640918360.

LCM Formula to Find Lowest Common Multiple of 161,440,889,456,847

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 440 x 889 x 456 x 847 = 24323639968320

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

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

889 : 1, 7, 127, 889

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

847 : 1, 7, 11, 77, 121, 847

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,440,889,456,847, is 1.

Now, the common factors can be found like this.

161:7x 23

440:2x 2x 2x 5x 11

889:7x 127

456:2x 2x 2x 3x 19

847:7x 11x 11

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

2x 2x 2x 7x 7x 11 = 4312

Therefore, the value for common factors is 4312.

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 = 24323639968320/(1x4312)

LCM = 24323639968320/4312

LCM = 5640918360

Thus, we can understand that the LCM of 161,440,889,456,847 is 5640918360.
