GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(216, 557) = 120312
GCD(216, 557) = ( 216 x 557 ) / 120312
= 216 / 557
= 216
Step2:
LCM(1, 368) = 368
GCD(1, 368) = ( 1 x 368 ) / 368
= 1 / 368
= 1
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 216, 557, 368, 978 is 1
