Given numbers are 920, 651, 979, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(920, 651) = 598920
GCD(920, 651) = ( 920 x 651 ) / 598920
= 920 / 651
= 920
Step2:
LCM(1, 979) = 979
GCD(1, 979) = ( 1 x 979 ) / 979
= 1 / 979
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 920, 651, 979, 561 is 1
