GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 864) = 61344
GCD(639, 864) = ( 639 x 864 ) / 61344
= 639 / 864
= 639
Step2:
LCM(9, 525) = 1575
GCD(9, 525) = ( 9 x 525 ) / 1575
= 9 / 525
= 9
Step3:
LCM(3, 725) = 2175
GCD(3, 725) = ( 3 x 725 ) / 2175
= 3 / 725
= 3
So, Greatest Common Divisor of 639, 864, 525, 725 is 1
