Given numbers are 645, 699, 731, 798
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 699) = 150285
GCD(645, 699) = ( 645 x 699 ) / 150285
= 645 / 699
= 645
Step2:
LCM(3, 731) = 2193
GCD(3, 731) = ( 3 x 731 ) / 2193
= 3 / 731
= 3
Step3:
LCM(1, 798) = 798
GCD(1, 798) = ( 1 x 798 ) / 798
= 1 / 798
= 1
So, Greatest Common Divisor of 645, 699, 731, 798 is 1
