GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(154, 847) = 1694
GCD(154, 847) = ( 154 x 847 ) / 1694
= 154 / 847
= 154
Step2:
LCM(77, 978) = 75306
GCD(77, 978) = ( 77 x 978 ) / 75306
= 77 / 978
= 77
Step3:
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
= 1 / 159
= 1
So, Greatest Common Divisor of 154, 847, 978, 159 is 1
