The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 690, 346, 68, 743
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 346) = 119370
GCD(690, 346) = ( 690 x 346 ) / 119370
= 690 / 346
= 690
Step2:
LCM(2, 68) = 68
GCD(2, 68) = ( 2 x 68 ) / 68
= 2 / 68
= 2
Step3:
LCM(2, 743) = 1486
GCD(2, 743) = ( 2 x 743 ) / 1486
= 2 / 743
= 2
So, Greatest Common Divisor of 690, 346, 68, 743 is 1
