Given numbers are 980, 860, 563, 531
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 860) = 42140
GCD(980, 860) = ( 980 x 860 ) / 42140
= 980 / 860
= 980
Step2:
LCM(20, 563) = 11260
GCD(20, 563) = ( 20 x 563 ) / 11260
= 20 / 563
= 20
Step3:
LCM(1, 531) = 531
GCD(1, 531) = ( 1 x 531 ) / 531
= 1 / 531
= 1
So, Greatest Common Divisor of 980, 860, 563, 531 is 1
