Given numbers are 373, 687, 21, 495
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(373, 687) = 256251
GCD(373, 687) = ( 373 x 687 ) / 256251
= 373 / 687
= 373
Step2:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
Step3:
LCM(1, 495) = 495
GCD(1, 495) = ( 1 x 495 ) / 495
= 1 / 495
= 1
So, Greatest Common Divisor of 373, 687, 21, 495 is 1
