Given numbers are 153, 772, 836, 392

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

Apply this formula for all numbers.

Step1:

LCM(153, 772) = 118116

GCD(153, 772) = ( 153 x 772 ) / 118116

= 153 / 772

= 153

Step2:

LCM(1, 836) = 836

GCD(1, 836) = ( 1 x 836 ) / 836

= 1 / 836

= 1

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 153, 772, 836, 392 is 1
