Given numbers are 978, 627, 206, 284
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 627) = 204402
GCD(978, 627) = ( 978 x 627 ) / 204402
= 978 / 627
= 978
Step2:
LCM(3, 206) = 618
GCD(3, 206) = ( 3 x 206 ) / 618
= 3 / 206
= 3
Step3:
LCM(1, 284) = 284
GCD(1, 284) = ( 1 x 284 ) / 284
= 1 / 284
= 1
So, Greatest Common Divisor of 978, 627, 206, 284 is 1
