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

Apply this formula for all numbers.

Step1:

LCM(521, 857) = 446497

GCD(521, 857) = ( 521 x 857 ) / 446497

= 521 / 857

= 521

Step2:

LCM(1, 70) = 70

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

= 1 / 70

= 1

So, Greatest Common Divisor of 521, 857, 70 is 1
