Given numbers are 754, 108, 168, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(754, 108) = 40716
GCD(754, 108) = ( 754 x 108 ) / 40716
= 754 / 108
= 754
Step2:
LCM(2, 168) = 168
GCD(2, 168) = ( 2 x 168 ) / 168
= 2 / 168
= 2
Step3:
LCM(2, 621) = 1242
GCD(2, 621) = ( 2 x 621 ) / 1242
= 2 / 621
= 2
So, Greatest Common Divisor of 754, 108, 168, 621 is 1
