Given numbers are 580, 775, 661, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(580, 775) = 89900
GCD(580, 775) = ( 580 x 775 ) / 89900
= 580 / 775
= 580
Step2:
LCM(5, 661) = 3305
GCD(5, 661) = ( 5 x 661 ) / 3305
= 5 / 661
= 5
Step3:
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
= 1 / 680
= 1
So, Greatest Common Divisor of 580, 775, 661, 680 is 1
