Given numbers are 645, 911, 792, 497
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 911) = 587595
GCD(645, 911) = ( 645 x 911 ) / 587595
= 645 / 911
= 645
Step2:
LCM(1, 792) = 792
GCD(1, 792) = ( 1 x 792 ) / 792
= 1 / 792
= 1
Step3:
LCM(1, 497) = 497
GCD(1, 497) = ( 1 x 497 ) / 497
= 1 / 497
= 1
So, Greatest Common Divisor of 645, 911, 792, 497 is 1
