GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 243) = 23085
GCD(855, 243) = ( 855 x 243 ) / 23085
= 855 / 243
= 855
Step2:
LCM(9, 742) = 6678
GCD(9, 742) = ( 9 x 742 ) / 6678
= 9 / 742
= 9
Step3:
LCM(1, 892) = 892
GCD(1, 892) = ( 1 x 892 ) / 892
= 1 / 892
= 1
So, Greatest Common Divisor of 855, 243, 742, 892 is 1
