Given numbers are 263, 491, 355, 120
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(263, 491) = 129133
GCD(263, 491) = ( 263 x 491 ) / 129133
= 263 / 491
= 263
Step2:
LCM(1, 355) = 355
GCD(1, 355) = ( 1 x 355 ) / 355
= 1 / 355
= 1
Step3:
LCM(1, 120) = 120
GCD(1, 120) = ( 1 x 120 ) / 120
= 1 / 120
= 1
So, Greatest Common Divisor of 263, 491, 355, 120 is 1
