Given numbers are 820, 985, 402, 949

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

Apply this formula for all numbers.

Step1:

LCM(820, 985) = 161540

GCD(820, 985) = ( 820 x 985 ) / 161540

= 820 / 985

= 820

Step2:

LCM(5, 402) = 2010

GCD(5, 402) = ( 5 x 402 ) / 2010

= 5 / 402

= 5

Step3:

LCM(1, 949) = 949

GCD(1, 949) = ( 1 x 949 ) / 949

= 1 / 949

= 1

So, Greatest Common Divisor of 820, 985, 402, 949 is 1
