Given numbers are 645, 659, 217, 292
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 659) = 425055
GCD(645, 659) = ( 645 x 659 ) / 425055
= 645 / 659
= 645
Step2:
LCM(1, 217) = 217
GCD(1, 217) = ( 1 x 217 ) / 217
= 1 / 217
= 1
Step3:
LCM(1, 292) = 292
GCD(1, 292) = ( 1 x 292 ) / 292
= 1 / 292
= 1
So, Greatest Common Divisor of 645, 659, 217, 292 is 1
