Given numbers are 247, 330, 971, 203
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 330) = 81510
GCD(247, 330) = ( 247 x 330 ) / 81510
= 247 / 330
= 247
Step2:
LCM(1, 971) = 971
GCD(1, 971) = ( 1 x 971 ) / 971
= 1 / 971
= 1
Step3:
LCM(1, 203) = 203
GCD(1, 203) = ( 1 x 203 ) / 203
= 1 / 203
= 1
So, Greatest Common Divisor of 247, 330, 971, 203 is 1
