Given numbers are 780, 246, 787, 349

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

Apply this formula for all numbers.

Step1:

LCM(780, 246) = 31980

GCD(780, 246) = ( 780 x 246 ) / 31980

= 780 / 246

= 780

Step2:

LCM(6, 787) = 4722

GCD(6, 787) = ( 6 x 787 ) / 4722

= 6 / 787

= 6

Step3:

LCM(1, 349) = 349

GCD(1, 349) = ( 1 x 349 ) / 349

= 1 / 349

= 1

So, Greatest Common Divisor of 780, 246, 787, 349 is 1
