Given numbers are 820, 940, 657, 658
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 940) = 38540
GCD(820, 940) = ( 820 x 940 ) / 38540
= 820 / 940
= 820
Step2:
LCM(20, 657) = 13140
GCD(20, 657) = ( 20 x 657 ) / 13140
= 20 / 657
= 20
Step3:
LCM(1, 658) = 658
GCD(1, 658) = ( 1 x 658 ) / 658
= 1 / 658
= 1
So, Greatest Common Divisor of 820, 940, 657, 658 is 1
