Given numbers are 258, 520, 696, 485
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(258, 520) = 67080
GCD(258, 520) = ( 258 x 520 ) / 67080
= 258 / 520
= 258
Step2:
LCM(2, 696) = 696
GCD(2, 696) = ( 2 x 696 ) / 696
= 2 / 696
= 2
Step3:
LCM(2, 485) = 970
GCD(2, 485) = ( 2 x 485 ) / 970
= 2 / 485
= 2
So, Greatest Common Divisor of 258, 520, 696, 485 is 1
