Given numbers are 152, 245, 981, 287
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(152, 245) = 37240
GCD(152, 245) = ( 152 x 245 ) / 37240
= 152 / 245
= 152
Step2:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
Step3:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
So, Greatest Common Divisor of 152, 245, 981, 287 is 1
