Given numbers are 531, 986, 565, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(531, 986) = 523566
GCD(531, 986) = ( 531 x 986 ) / 523566
= 531 / 986
= 531
Step2:
LCM(1, 565) = 565
GCD(1, 565) = ( 1 x 565 ) / 565
= 1 / 565
= 1
Step3:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
So, Greatest Common Divisor of 531, 986, 565, 145 is 1
