Given numbers are 742, 530, 551, 170

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

Apply this formula for all numbers.

Step1:

LCM(742, 530) = 3710

GCD(742, 530) = ( 742 x 530 ) / 3710

= 742 / 530

= 742

Step2:

LCM(106, 551) = 58406

GCD(106, 551) = ( 106 x 551 ) / 58406

= 106 / 551

= 106

Step3:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

So, Greatest Common Divisor of 742, 530, 551, 170 is 1
