Given numbers are 243, 434, 139, 754
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 434) = 105462
GCD(243, 434) = ( 243 x 434 ) / 105462
= 243 / 434
= 243
Step2:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
Step3:
LCM(1, 754) = 754
GCD(1, 754) = ( 1 x 754 ) / 754
= 1 / 754
= 1
So, Greatest Common Divisor of 243, 434, 139, 754 is 1
