GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 735) = 22785
GCD(217, 735) = ( 217 x 735 ) / 22785
= 217 / 735
= 217
Step2:
LCM(7, 978) = 6846
GCD(7, 978) = ( 7 x 978 ) / 6846
= 7 / 978
= 7
Step3:
LCM(1, 458) = 458
GCD(1, 458) = ( 1 x 458 ) / 458
= 1 / 458
= 1
So, Greatest Common Divisor of 217, 735, 978, 458 is 1
