GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 872) = 136904
GCD(628, 872) = ( 628 x 872 ) / 136904
= 628 / 872
= 628
Step2:
LCM(4, 809) = 3236
GCD(4, 809) = ( 4 x 809 ) / 3236
= 4 / 809
= 4
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 628, 872, 809, 620 is 1
