Given numbers are 488, 316, 403, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(488, 316) = 38552
GCD(488, 316) = ( 488 x 316 ) / 38552
= 488 / 316
= 488
Step2:
LCM(4, 403) = 1612
GCD(4, 403) = ( 4 x 403 ) / 1612
= 4 / 403
= 4
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 488, 316, 403, 215 is 1
