Given numbers are 821, 175, 406, 757

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

Apply this formula for all numbers.

Step1:

LCM(821, 175) = 143675

GCD(821, 175) = ( 821 x 175 ) / 143675

= 821 / 175

= 821

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 757) = 757

GCD(1, 757) = ( 1 x 757 ) / 757

= 1 / 757

= 1

So, Greatest Common Divisor of 821, 175, 406, 757 is 1
