GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 486) = 79218
GCD(978, 486) = ( 978 x 486 ) / 79218
= 978 / 486
= 978
Step2:
LCM(6, 498) = 498
GCD(6, 498) = ( 6 x 498 ) / 498
= 6 / 498
= 6
Step3:
LCM(6, 805) = 4830
GCD(6, 805) = ( 6 x 805 ) / 4830
= 6 / 805
= 6
So, Greatest Common Divisor of 978, 486, 498, 805 is 1
