Given numbers are 690, 567, 361, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 567) = 130410
GCD(690, 567) = ( 690 x 567 ) / 130410
= 690 / 567
= 690
Step2:
LCM(3, 361) = 1083
GCD(3, 361) = ( 3 x 361 ) / 1083
= 3 / 361
= 3
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 690, 567, 361, 805 is 1
