Given numbers are 448, 379, 815, 691
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(448, 379) = 169792
GCD(448, 379) = ( 448 x 379 ) / 169792
= 448 / 379
= 448
Step2:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
Step3:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
So, Greatest Common Divisor of 448, 379, 815, 691 is 1
