Given numbers are 620, 661, 326, 656
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 661) = 409820
GCD(620, 661) = ( 620 x 661 ) / 409820
= 620 / 661
= 620
Step2:
LCM(1, 326) = 326
GCD(1, 326) = ( 1 x 326 ) / 326
= 1 / 326
= 1
Step3:
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
= 1 / 656
= 1
So, Greatest Common Divisor of 620, 661, 326, 656 is 1
