GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 558) = 16182
GCD(261, 558) = ( 261 x 558 ) / 16182
= 261 / 558
= 261
Step2:
LCM(9, 928) = 8352
GCD(9, 928) = ( 9 x 928 ) / 8352
= 9 / 928
= 9
Step3:
LCM(1, 580) = 580
GCD(1, 580) = ( 1 x 580 ) / 580
= 1 / 580
= 1
So, Greatest Common Divisor of 261, 558, 928, 580 is 1
