GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(872, 639) = 557208
GCD(872, 639) = ( 872 x 639 ) / 557208
= 872 / 639
= 872
Step2:
LCM(1, 341) = 341
GCD(1, 341) = ( 1 x 341 ) / 341
= 1 / 341
= 1
Step3:
LCM(1, 276) = 276
GCD(1, 276) = ( 1 x 276 ) / 276
= 1 / 276
= 1
So, Greatest Common Divisor of 872, 639, 341, 276 is 1
