Given numbers are 235, 945, 731, 121
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(235, 945) = 44415
GCD(235, 945) = ( 235 x 945 ) / 44415
= 235 / 945
= 235
Step2:
LCM(5, 731) = 3655
GCD(5, 731) = ( 5 x 731 ) / 3655
= 5 / 731
= 5
Step3:
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
= 1 / 121
= 1
So, Greatest Common Divisor of 235, 945, 731, 121 is 1
