Given numbers are 238, 777, 440, 654
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(238, 777) = 26418
GCD(238, 777) = ( 238 x 777 ) / 26418
= 238 / 777
= 238
Step2:
LCM(7, 440) = 3080
GCD(7, 440) = ( 7 x 440 ) / 3080
= 7 / 440
= 7
Step3:
LCM(1, 654) = 654
GCD(1, 654) = ( 1 x 654 ) / 654
= 1 / 654
= 1
So, Greatest Common Divisor of 238, 777, 440, 654 is 1
