Given numbers are 680, 128, 810, 448
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 128) = 10880
GCD(680, 128) = ( 680 x 128 ) / 10880
= 680 / 128
= 680
Step2:
LCM(8, 810) = 3240
GCD(8, 810) = ( 8 x 810 ) / 3240
= 8 / 810
= 8
Step3:
LCM(2, 448) = 448
GCD(2, 448) = ( 2 x 448 ) / 448
= 2 / 448
= 2
So, Greatest Common Divisor of 680, 128, 810, 448 is 2
