Given numbers are 638, 882, 631, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 882) = 281358
GCD(638, 882) = ( 638 x 882 ) / 281358
= 638 / 882
= 638
Step2:
LCM(2, 631) = 1262
GCD(2, 631) = ( 2 x 631 ) / 1262
= 2 / 631
= 2
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 638, 882, 631, 215 is 1
