Given numbers are 390, 177, 529, 705

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

Apply this formula for all numbers.

Step1:

LCM(390, 177) = 23010

GCD(390, 177) = ( 390 x 177 ) / 23010

= 390 / 177

= 390

Step2:

LCM(3, 529) = 1587

GCD(3, 529) = ( 3 x 529 ) / 1587

= 3 / 529

= 3

Step3:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1

So, Greatest Common Divisor of 390, 177, 529, 705 is 1
