Given numbers are 780, 949, 838, 181

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

Apply this formula for all numbers.

Step1:

LCM(780, 949) = 56940

GCD(780, 949) = ( 780 x 949 ) / 56940

= 780 / 949

= 780

Step2:

LCM(13, 838) = 10894

GCD(13, 838) = ( 13 x 838 ) / 10894

= 13 / 838

= 13

Step3:

LCM(1, 181) = 181

GCD(1, 181) = ( 1 x 181 ) / 181

= 1 / 181

= 1

So, Greatest Common Divisor of 780, 949, 838, 181 is 1
