GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(272, 978) = 133008
GCD(272, 978) = ( 272 x 978 ) / 133008
= 272 / 978
= 272
Step2:
LCM(2, 891) = 1782
GCD(2, 891) = ( 2 x 891 ) / 1782
= 2 / 891
= 2
Step3:
LCM(1, 801) = 801
GCD(1, 801) = ( 1 x 801 ) / 801
= 1 / 801
= 1
So, Greatest Common Divisor of 272, 978, 891, 801 is 1
