Given numbers are 770, 128, 198, 993

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

Apply this formula for all numbers.

Step1:

LCM(770, 128) = 49280

GCD(770, 128) = ( 770 x 128 ) / 49280

= 770 / 128

= 770

Step2:

LCM(2, 198) = 198

GCD(2, 198) = ( 2 x 198 ) / 198

= 2 / 198

= 2

Step3:

LCM(2, 993) = 1986

GCD(2, 993) = ( 2 x 993 ) / 1986

= 2 / 993

= 2

So, Greatest Common Divisor of 770, 128, 198, 993 is 1
