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
