Given numbers are 978, 715, 281, 173
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 715) = 699270
GCD(978, 715) = ( 978 x 715 ) / 699270
= 978 / 715
= 978
Step2:
LCM(1, 281) = 281
GCD(1, 281) = ( 1 x 281 ) / 281
= 1 / 281
= 1
Step3:
LCM(1, 173) = 173
GCD(1, 173) = ( 1 x 173 ) / 173
= 1 / 173
= 1
So, Greatest Common Divisor of 978, 715, 281, 173 is 1
