Given numbers are 821, 425, 661, 708

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

Apply this formula for all numbers.

Step1:

LCM(821, 425) = 348925

GCD(821, 425) = ( 821 x 425 ) / 348925

= 821 / 425

= 821

Step2:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

Step3:

LCM(1, 708) = 708

GCD(1, 708) = ( 1 x 708 ) / 708

= 1 / 708

= 1

So, Greatest Common Divisor of 821, 425, 661, 708 is 1
