GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 978) = 47922
GCD(147, 978) = ( 147 x 978 ) / 47922
= 147 / 978
= 147
Step2:
LCM(3, 445) = 1335
GCD(3, 445) = ( 3 x 445 ) / 1335
= 3 / 445
= 3
Step3:
LCM(1, 791) = 791
GCD(1, 791) = ( 1 x 791 ) / 791
= 1 / 791
= 1
So, Greatest Common Divisor of 147, 978, 445, 791 is 1
