Given numbers are 427, 672, 285, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(427, 672) = 40992
GCD(427, 672) = ( 427 x 672 ) / 40992
= 427 / 672
= 427
Step2:
LCM(7, 285) = 1995
GCD(7, 285) = ( 7 x 285 ) / 1995
= 7 / 285
= 7
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 427, 672, 285, 641 is 1
