Given numbers are 260, 644, 794, 657
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(260, 644) = 41860
GCD(260, 644) = ( 260 x 644 ) / 41860
= 260 / 644
= 260
Step2:
LCM(4, 794) = 1588
GCD(4, 794) = ( 4 x 794 ) / 1588
= 4 / 794
= 4
Step3:
LCM(2, 657) = 1314
GCD(2, 657) = ( 2 x 657 ) / 1314
= 2 / 657
= 2
So, Greatest Common Divisor of 260, 644, 794, 657 is 1
