Given numbers are 664, 306, 669, 520
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(664, 306) = 101592
GCD(664, 306) = ( 664 x 306 ) / 101592
= 664 / 306
= 664
Step2:
LCM(2, 669) = 1338
GCD(2, 669) = ( 2 x 669 ) / 1338
= 2 / 669
= 2
Step3:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
So, Greatest Common Divisor of 664, 306, 669, 520 is 1
