GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(664, 921) = 611544
GCD(664, 921) = ( 664 x 921 ) / 611544
= 664 / 921
= 664
Step2:
LCM(1, 623) = 623
GCD(1, 623) = ( 1 x 623 ) / 623
= 1 / 623
= 1
Step3:
LCM(1, 486) = 486
GCD(1, 486) = ( 1 x 486 ) / 486
= 1 / 486
= 1
So, Greatest Common Divisor of 664, 921, 623, 486 is 1
