GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 127) = 31115
GCD(245, 127) = ( 245 x 127 ) / 31115
= 245 / 127
= 245
Step2:
LCM(1, 928) = 928
GCD(1, 928) = ( 1 x 928 ) / 928
= 1 / 928
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 245, 127, 928, 689 is 1
