Given numbers are 747, 777, 785, 847
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(747, 777) = 193473
GCD(747, 777) = ( 747 x 777 ) / 193473
= 747 / 777
= 747
Step2:
LCM(3, 785) = 2355
GCD(3, 785) = ( 3 x 785 ) / 2355
= 3 / 785
= 3
Step3:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
So, Greatest Common Divisor of 747, 777, 785, 847 is 1
