Given numbers are 308, 920, 856, 197
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(308, 920) = 70840
GCD(308, 920) = ( 308 x 920 ) / 70840
= 308 / 920
= 308
Step2:
LCM(4, 856) = 856
GCD(4, 856) = ( 4 x 856 ) / 856
= 4 / 856
= 4
Step3:
LCM(4, 197) = 788
GCD(4, 197) = ( 4 x 197 ) / 788
= 4 / 197
= 4
So, Greatest Common Divisor of 308, 920, 856, 197 is 1
