Find LCM of 680,473,803,663,172 with Prime Factorization
2 | 680, 473, 803, 663, 172 |
2 | 340, 473, 803, 663, 86 |
11 | 170, 473, 803, 663, 43 |
17 | 170, 43, 73, 663, 43 |
43 | 10, 43, 73, 39, 43 |
10, 1, 73, 39, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 17 x 43 x 10 x 1 x 73 x 39 x 1 = 915709080
Therefore, the lowest common multiple of 680,473,803,663,172 is 915709080.
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.
680 x 473 x 803 x 663 x 172 = 29452866849120
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
473 : 1, 11, 43, 473
803 : 1, 11, 73, 803
663 : 1, 3, 13, 17, 39, 51, 221, 663
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,473,803,663,172, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
473:11x 43
803:11x 73
663:3x 13x 17
172:2x 2x 43
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 11x 17x 43 = 32164
Therefore, the value for common factors is 32164.
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 = 29452866849120/(1x32164)
LCM = 29452866849120/32164
LCM = 915709080
Thus, we can understand that the LCM of 680,473,803,663,172 is 915709080.
