GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 286) = 92378
GCD(646, 286) = ( 646 x 286 ) / 92378
= 646 / 286
= 646
Step2:
LCM(2, 969) = 1938
GCD(2, 969) = ( 2 x 969 ) / 1938
= 2 / 969
= 2
Step3:
LCM(1, 739) = 739
GCD(1, 739) = ( 1 x 739 ) / 739
= 1 / 739
= 1
So, Greatest Common Divisor of 646, 286, 969, 739 is 1
