Given numbers are 156, 371, 243, 839
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 371) = 57876
GCD(156, 371) = ( 156 x 371 ) / 57876
= 156 / 371
= 156
Step2:
LCM(1, 243) = 243
GCD(1, 243) = ( 1 x 243 ) / 243
= 1 / 243
= 1
Step3:
LCM(1, 839) = 839
GCD(1, 839) = ( 1 x 839 ) / 839
= 1 / 839
= 1
So, Greatest Common Divisor of 156, 371, 243, 839 is 1
