Given numbers are 861, 623, 168, 754
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 623) = 76629
GCD(861, 623) = ( 861 x 623 ) / 76629
= 861 / 623
= 861
Step2:
LCM(7, 168) = 168
GCD(7, 168) = ( 7 x 168 ) / 168
= 7 / 168
= 7
Step3:
LCM(7, 754) = 5278
GCD(7, 754) = ( 7 x 754 ) / 5278
= 7 / 754
= 7
So, Greatest Common Divisor of 861, 623, 168, 754 is 1
