Given numbers are 923, 530, 849, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(923, 530) = 489190
GCD(923, 530) = ( 923 x 530 ) / 489190
= 923 / 530
= 923
Step2:
LCM(1, 849) = 849
GCD(1, 849) = ( 1 x 849 ) / 849
= 1 / 849
= 1
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 923, 530, 849, 639 is 1
