Given numbers are 117, 780, 827, 971

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

Apply this formula for all numbers.

Step1:

LCM(117, 780) = 2340

GCD(117, 780) = ( 117 x 780 ) / 2340

= 117 / 780

= 117

Step2:

LCM(39, 827) = 32253

GCD(39, 827) = ( 39 x 827 ) / 32253

= 39 / 827

= 39

Step3:

LCM(1, 971) = 971

GCD(1, 971) = ( 1 x 971 ) / 971

= 1 / 971

= 1

So, Greatest Common Divisor of 117, 780, 827, 971 is 1
