GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(612, 690) = 70380
GCD(612, 690) = ( 612 x 690 ) / 70380
= 612 / 690
= 612
Step2:
LCM(6, 891) = 1782
GCD(6, 891) = ( 6 x 891 ) / 1782
= 6 / 891
= 6
Step3:
LCM(3, 797) = 2391
GCD(3, 797) = ( 3 x 797 ) / 2391
= 3 / 797
= 3
So, Greatest Common Divisor of 612, 690, 891, 797 is 1
