Given numbers are 155, 530, 704, 947

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

Apply this formula for all numbers.

Step1:

LCM(155, 530) = 16430

GCD(155, 530) = ( 155 x 530 ) / 16430

= 155 / 530

= 155

Step2:

LCM(5, 704) = 3520

GCD(5, 704) = ( 5 x 704 ) / 3520

= 5 / 704

= 5

Step3:

LCM(1, 947) = 947

GCD(1, 947) = ( 1 x 947 ) / 947

= 1 / 947

= 1

So, Greatest Common Divisor of 155, 530, 704, 947 is 1
