GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(289, 628) = 181492
GCD(289, 628) = ( 289 x 628 ) / 181492
= 289 / 628
= 289
Step2:
LCM(1, 258) = 258
GCD(1, 258) = ( 1 x 258 ) / 258
= 1 / 258
= 1
Step3:
LCM(1, 977) = 977
GCD(1, 977) = ( 1 x 977 ) / 977
= 1 / 977
= 1
So, Greatest Common Divisor of 289, 628, 258, 977 is 1
