GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(325, 985) = 64025
GCD(325, 985) = ( 325 x 985 ) / 64025
= 325 / 985
= 325
Step2:
LCM(5, 75) = 75
GCD(5, 75) = ( 5 x 75 ) / 75
= 5 / 75
= 5
Step3:
LCM(5, 690) = 690
GCD(5, 690) = ( 5 x 690 ) / 690
= 5 / 690
= 5
So, Greatest Common Divisor of 325, 985, 75, 690 is 5
