GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 668) = 266532
GCD(399, 668) = ( 399 x 668 ) / 266532
= 399 / 668
= 399
Step2:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
Step3:
LCM(1, 525) = 525
GCD(1, 525) = ( 1 x 525 ) / 525
= 1 / 525
= 1
So, Greatest Common Divisor of 399, 668, 805, 525 is 1
