Given numbers are 821, 813, 70, 532

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

Apply this formula for all numbers.

Step1:

LCM(821, 813) = 667473

GCD(821, 813) = ( 821 x 813 ) / 667473

= 821 / 813

= 821

Step2:

LCM(1, 70) = 70

GCD(1, 70) = ( 1 x 70 ) / 70

= 1 / 70

= 1

Step3:

LCM(1, 532) = 532

GCD(1, 532) = ( 1 x 532 ) / 532

= 1 / 532

= 1

So, Greatest Common Divisor of 821, 813, 70, 532 is 1
