Given numbers are 646, 196, 727, 246
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 196) = 63308
GCD(646, 196) = ( 646 x 196 ) / 63308
= 646 / 196
= 646
Step2:
LCM(2, 727) = 1454
GCD(2, 727) = ( 2 x 727 ) / 1454
= 2 / 727
= 2
Step3:
LCM(1, 246) = 246
GCD(1, 246) = ( 1 x 246 ) / 246
= 1 / 246
= 1
So, Greatest Common Divisor of 646, 196, 727, 246 is 1
