Given numbers are 821, 578, 383, 342

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

Apply this formula for all numbers.

Step1:

LCM(821, 578) = 474538

GCD(821, 578) = ( 821 x 578 ) / 474538

= 821 / 578

= 821

Step2:

LCM(1, 383) = 383

GCD(1, 383) = ( 1 x 383 ) / 383

= 1 / 383

= 1

Step3:

LCM(1, 342) = 342

GCD(1, 342) = ( 1 x 342 ) / 342

= 1 / 342

= 1

So, Greatest Common Divisor of 821, 578, 383, 342 is 1
