GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(664, 688) = 57104
GCD(664, 688) = ( 664 x 688 ) / 57104
= 664 / 688
= 664
Step2:
LCM(8, 225) = 1800
GCD(8, 225) = ( 8 x 225 ) / 1800
= 8 / 225
= 8
Step3:
LCM(1, 322) = 322
GCD(1, 322) = ( 1 x 322 ) / 322
= 1 / 322
= 1
So, Greatest Common Divisor of 664, 688, 225, 322 is 1
