Given numbers are 491, 290, 955, 315
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 290) = 142390
GCD(491, 290) = ( 491 x 290 ) / 142390
= 491 / 290
= 491
Step2:
LCM(1, 955) = 955
GCD(1, 955) = ( 1 x 955 ) / 955
= 1 / 955
= 1
Step3:
LCM(1, 315) = 315
GCD(1, 315) = ( 1 x 315 ) / 315
= 1 / 315
= 1
So, Greatest Common Divisor of 491, 290, 955, 315 is 1
