Given numbers are 206, 687, 438, 265
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(206, 687) = 141522
GCD(206, 687) = ( 206 x 687 ) / 141522
= 206 / 687
= 206
Step2:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
Step3:
LCM(1, 265) = 265
GCD(1, 265) = ( 1 x 265 ) / 265
= 1 / 265
= 1
So, Greatest Common Divisor of 206, 687, 438, 265 is 1
