GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 529) = 517362
GCD(978, 529) = ( 978 x 529 ) / 517362
= 978 / 529
= 978
Step2:
LCM(1, 786) = 786
GCD(1, 786) = ( 1 x 786 ) / 786
= 1 / 786
= 1
Step3:
LCM(1, 248) = 248
GCD(1, 248) = ( 1 x 248 ) / 248
= 1 / 248
= 1
So, Greatest Common Divisor of 978, 529, 786, 248 is 1
