Given numbers are 665, 651, 994, 400
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 651) = 61845
GCD(665, 651) = ( 665 x 651 ) / 61845
= 665 / 651
= 665
Step2:
LCM(7, 994) = 994
GCD(7, 994) = ( 7 x 994 ) / 994
= 7 / 994
= 7
Step3:
LCM(7, 400) = 2800
GCD(7, 400) = ( 7 x 400 ) / 2800
= 7 / 400
= 7
So, Greatest Common Divisor of 665, 651, 994, 400 is 1
