Given numbers are 45, 61, 57
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(45, 61) = 2745
GCD(45, 61) = ( 45 x 61 ) / 2745
= 45 / 61
= 45
Step2:
LCM(1, 57) = 57
GCD(1, 57) = ( 1 x 57 ) / 57
= 1 / 57
= 1
So, Greatest Common Divisor of 45, 61, 57 is 1
