GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(664, 809) = 537176
GCD(664, 809) = ( 664 x 809 ) / 537176
= 664 / 809
= 664
Step2:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
Step3:
LCM(1, 228) = 228
GCD(1, 228) = ( 1 x 228 ) / 228
= 1 / 228
= 1
So, Greatest Common Divisor of 664, 809, 128, 228 is 1
