Given numbers are 788, 478, 620, 711
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(788, 478) = 188332
GCD(788, 478) = ( 788 x 478 ) / 188332
= 788 / 478
= 788
Step2:
LCM(2, 620) = 620
GCD(2, 620) = ( 2 x 620 ) / 620
= 2 / 620
= 2
Step3:
LCM(2, 711) = 1422
GCD(2, 711) = ( 2 x 711 ) / 1422
= 2 / 711
= 2
So, Greatest Common Divisor of 788, 478, 620, 711 is 1
