GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(580, 660) = 19140
GCD(580, 660) = ( 580 x 660 ) / 19140
= 580 / 660
= 580
Step2:
LCM(20, 42) = 420
GCD(20, 42) = ( 20 x 42 ) / 420
= 20 / 42
= 20
Step3:
LCM(2, 856) = 856
GCD(2, 856) = ( 2 x 856 ) / 856
= 2 / 856
= 2
So, Greatest Common Divisor of 580, 660, 42, 856 is 2
