Given numbers are 255, 231, 745, 715
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 231) = 19635
GCD(255, 231) = ( 255 x 231 ) / 19635
= 255 / 231
= 255
Step2:
LCM(3, 745) = 2235
GCD(3, 745) = ( 3 x 745 ) / 2235
= 3 / 745
= 3
Step3:
LCM(1, 715) = 715
GCD(1, 715) = ( 1 x 715 ) / 715
= 1 / 715
= 1
So, Greatest Common Divisor of 255, 231, 745, 715 is 1
