Given numbers are 530, 385, 891, 715

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

Apply this formula for all numbers.

Step1:

LCM(530, 385) = 40810

GCD(530, 385) = ( 530 x 385 ) / 40810

= 530 / 385

= 530

Step2:

LCM(5, 891) = 4455

GCD(5, 891) = ( 5 x 891 ) / 4455

= 5 / 891

= 5

Step3:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

So, Greatest Common Divisor of 530, 385, 891, 715 is 1
