GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 228) = 3876
GCD(646, 228) = ( 646 x 228 ) / 3876
= 646 / 228
= 646
Step2:
LCM(38, 207) = 7866
GCD(38, 207) = ( 38 x 207 ) / 7866
= 38 / 207
= 38
So, Greatest Common Divisor of 646, 228, 207 is 1
