Given numbers are 280, 497, 877, 261
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 497) = 19880
GCD(280, 497) = ( 280 x 497 ) / 19880
= 280 / 497
= 280
Step2:
LCM(7, 877) = 6139
GCD(7, 877) = ( 7 x 877 ) / 6139
= 7 / 877
= 7
Step3:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
So, Greatest Common Divisor of 280, 497, 877, 261 is 1
