GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(128, 920) = 14720
GCD(128, 920) = ( 128 x 920 ) / 14720
= 128 / 920
= 128
Step2:
LCM(8, 842) = 3368
GCD(8, 842) = ( 8 x 842 ) / 3368
= 8 / 842
= 8
Step3:
LCM(2, 847) = 1694
GCD(2, 847) = ( 2 x 847 ) / 1694
= 2 / 847
= 2
So, Greatest Common Divisor of 128, 920, 842, 847 is 1
