Given numbers are 828, 772, 787, 442

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

Apply this formula for all numbers.

Step1:

LCM(828, 772) = 159804

GCD(828, 772) = ( 828 x 772 ) / 159804

= 828 / 772

= 828

Step2:

LCM(4, 787) = 3148

GCD(4, 787) = ( 4 x 787 ) / 3148

= 4 / 787

= 4

Step3:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

So, Greatest Common Divisor of 828, 772, 787, 442 is 1
