Given numbers are 442, 969, 157, 820

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

Apply this formula for all numbers.

Step1:

LCM(442, 969) = 25194

GCD(442, 969) = ( 442 x 969 ) / 25194

= 442 / 969

= 442

Step2:

LCM(17, 157) = 2669

GCD(17, 157) = ( 17 x 157 ) / 2669

= 17 / 157

= 17

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 442, 969, 157, 820 is 1
