GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(447, 861) = 128289
GCD(447, 861) = ( 447 x 861 ) / 128289
= 447 / 861
= 447
Step2:
LCM(3, 320) = 960
GCD(3, 320) = ( 3 x 320 ) / 960
= 3 / 320
= 3
Step3:
LCM(1, 357) = 357
GCD(1, 357) = ( 1 x 357 ) / 357
= 1 / 357
= 1
So, Greatest Common Divisor of 447, 861, 320, 357 is 1
