GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(751, 978) = 734478
GCD(751, 978) = ( 751 x 978 ) / 734478
= 751 / 978
= 751
Step2:
LCM(1, 788) = 788
GCD(1, 788) = ( 1 x 788 ) / 788
= 1 / 788
= 1
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 751, 978, 788, 643 is 1
