Given numbers are 245, 255, 22, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 255) = 12495
GCD(245, 255) = ( 245 x 255 ) / 12495
= 245 / 255
= 245
Step2:
LCM(5, 22) = 110
GCD(5, 22) = ( 5 x 22 ) / 110
= 5 / 22
= 5
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 245, 255, 22, 215 is 1
