Given numbers are 206, 972, 942, 331
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(206, 972) = 100116
GCD(206, 972) = ( 206 x 972 ) / 100116
= 206 / 972
= 206
Step2:
LCM(2, 942) = 942
GCD(2, 942) = ( 2 x 942 ) / 942
= 2 / 942
= 2
Step3:
LCM(2, 331) = 662
GCD(2, 331) = ( 2 x 331 ) / 662
= 2 / 331
= 2
So, Greatest Common Divisor of 206, 972, 942, 331 is 1
