Given numbers are 690, 474, 756, 163
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 474) = 54510
GCD(690, 474) = ( 690 x 474 ) / 54510
= 690 / 474
= 690
Step2:
LCM(6, 756) = 756
GCD(6, 756) = ( 6 x 756 ) / 756
= 6 / 756
= 6
Step3:
LCM(6, 163) = 978
GCD(6, 163) = ( 6 x 163 ) / 978
= 6 / 163
= 6
So, Greatest Common Divisor of 690, 474, 756, 163 is 1
