GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(369, 138) = 16974
GCD(369, 138) = ( 369 x 138 ) / 16974
= 369 / 138
= 369
Step2:
LCM(3, 637) = 1911
GCD(3, 637) = ( 3 x 637 ) / 1911
= 3 / 637
= 3
Step3:
LCM(1, 853) = 853
GCD(1, 853) = ( 1 x 853 ) / 853
= 1 / 853
= 1
So, Greatest Common Divisor of 369, 138, 637, 853 is 1
