Given numbers are 690, 545, 871, 954
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 545) = 75210
GCD(690, 545) = ( 690 x 545 ) / 75210
= 690 / 545
= 690
Step2:
LCM(5, 871) = 4355
GCD(5, 871) = ( 5 x 871 ) / 4355
= 5 / 871
= 5
Step3:
LCM(1, 954) = 954
GCD(1, 954) = ( 1 x 954 ) / 954
= 1 / 954
= 1
So, Greatest Common Divisor of 690, 545, 871, 954 is 1
