Given numbers are 720, 880, 324, 842
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 880) = 7920
GCD(720, 880) = ( 720 x 880 ) / 7920
= 720 / 880
= 720
Step2:
LCM(80, 324) = 6480
GCD(80, 324) = ( 80 x 324 ) / 6480
= 80 / 324
= 80
Step3:
LCM(4, 842) = 1684
GCD(4, 842) = ( 4 x 842 ) / 1684
= 4 / 842
= 4
So, Greatest Common Divisor of 720, 880, 324, 842 is 2
