Given numbers are 820, 235, 755, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 235) = 38540
GCD(820, 235) = ( 820 x 235 ) / 38540
= 820 / 235
= 820
Step2:
LCM(5, 755) = 755
GCD(5, 755) = ( 5 x 755 ) / 755
= 5 / 755
= 5
Step3:
LCM(5, 680) = 680
GCD(5, 680) = ( 5 x 680 ) / 680
= 5 / 680
= 5
So, Greatest Common Divisor of 820, 235, 755, 680 is 5
