Given numbers are 651, 153, 223, 978
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(651, 153) = 33201
GCD(651, 153) = ( 651 x 153 ) / 33201
= 651 / 153
= 651
Step2:
LCM(3, 223) = 669
GCD(3, 223) = ( 3 x 223 ) / 669
= 3 / 223
= 3
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 651, 153, 223, 978 is 1
