Given numbers are 782, 621, 704, 198

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

Apply this formula for all numbers.

Step1:

LCM(782, 621) = 21114

GCD(782, 621) = ( 782 x 621 ) / 21114

= 782 / 621

= 782

Step2:

LCM(23, 704) = 16192

GCD(23, 704) = ( 23 x 704 ) / 16192

= 23 / 704

= 23

Step3:

LCM(1, 198) = 198

GCD(1, 198) = ( 1 x 198 ) / 198

= 1 / 198

= 1

So, Greatest Common Divisor of 782, 621, 704, 198 is 1
