The factors of 645 are: 1, 3, 5, 15, 43, 129, 215, 645.
The sum of 483 and 162 is 645.
645
445
645 - 151 = 494 494 / 2 = 247 247 + 151 = 398 Which means: 398 + 247 = 645 and 398 - 247 = 151
398 and 247.
a + b = 645 a - b = 151 Add: 2a = 796 a= 398, making b = 247
247 + 398 = 645398 - 247 = 151Therefore the two numbers which add together to make 645 and have a difference of 151 are 247 and 398.
