Given numbers are 690, 309, 572, 986
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 309) = 71070
GCD(690, 309) = ( 690 x 309 ) / 71070
= 690 / 309
= 690
Step2:
LCM(3, 572) = 1716
GCD(3, 572) = ( 3 x 572 ) / 1716
= 3 / 572
= 3
Step3:
LCM(1, 986) = 986
GCD(1, 986) = ( 1 x 986 ) / 986
= 1 / 986
= 1
So, Greatest Common Divisor of 690, 309, 572, 986 is 1
