Given numbers are 491, 263, 830, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 263) = 129133
GCD(491, 263) = ( 491 x 263 ) / 129133
= 491 / 263
= 491
Step2:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 491, 263, 830, 155 is 1
