Given numbers are 558, 689, 570, 661

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

Apply this formula for all numbers.

Step1:

LCM(558, 689) = 384462

GCD(558, 689) = ( 558 x 689 ) / 384462

= 558 / 689

= 558

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 558, 689, 570, 661 is 1
