Given numbers are 771, 888, 643, 998

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(771, 888) = 228216

GCD(771, 888) = ( 771 x 888 ) / 228216

= 771 / 888

= 771

Step2:

LCM(3, 643) = 1929

GCD(3, 643) = ( 3 x 643 ) / 1929

= 3 / 643

= 3

Step3:

LCM(1, 998) = 998

GCD(1, 998) = ( 1 x 998 ) / 998

= 1 / 998

= 1

So, Greatest Common Divisor of 771, 888, 643, 998 is 1
