Given numbers are 905, 715, 657, 284
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 715) = 129415
GCD(905, 715) = ( 905 x 715 ) / 129415
= 905 / 715
= 905
Step2:
LCM(5, 657) = 3285
GCD(5, 657) = ( 5 x 657 ) / 3285
= 5 / 657
= 5
Step3:
LCM(1, 284) = 284
GCD(1, 284) = ( 1 x 284 ) / 284
= 1 / 284
= 1
So, Greatest Common Divisor of 905, 715, 657, 284 is 1
