GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 791) = 27685
GCD(245, 791) = ( 245 x 791 ) / 27685
= 245 / 791
= 245
Step2:
LCM(7, 145) = 1015
GCD(7, 145) = ( 7 x 145 ) / 1015
= 7 / 145
= 7
Step3:
LCM(1, 943) = 943
GCD(1, 943) = ( 1 x 943 ) / 943
= 1 / 943
= 1
So, Greatest Common Divisor of 245, 791, 145, 943 is 1
