GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(756, 777) = 27972
GCD(756, 777) = ( 756 x 777 ) / 27972
= 756 / 777
= 756
Step2:
LCM(21, 247) = 5187
GCD(21, 247) = ( 21 x 247 ) / 5187
= 21 / 247
= 21
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 756, 777, 247, 978 is 1
