Given numbers are 168, 964, 985, 100
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(168, 964) = 40488
GCD(168, 964) = ( 168 x 964 ) / 40488
= 168 / 964
= 168
Step2:
LCM(4, 985) = 3940
GCD(4, 985) = ( 4 x 985 ) / 3940
= 4 / 985
= 4
Step3:
LCM(1, 100) = 100
GCD(1, 100) = ( 1 x 100 ) / 100
= 1 / 100
= 1
So, Greatest Common Divisor of 168, 964, 985, 100 is 1
