Given numbers are 815, 931, 989, 602
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 931) = 758765
GCD(815, 931) = ( 815 x 931 ) / 758765
= 815 / 931
= 815
Step2:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
Step3:
LCM(1, 602) = 602
GCD(1, 602) = ( 1 x 602 ) / 602
= 1 / 602
= 1
So, Greatest Common Divisor of 815, 931, 989, 602 is 1
