GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 775) = 5425
GCD(217, 775) = ( 217 x 775 ) / 5425
= 217 / 775
= 217
Step2:
LCM(31, 791) = 24521
GCD(31, 791) = ( 31 x 791 ) / 24521
= 31 / 791
= 31
Step3:
LCM(1, 992) = 992
GCD(1, 992) = ( 1 x 992 ) / 992
= 1 / 992
= 1
So, Greatest Common Divisor of 217, 775, 791, 992 is 1
