Given numbers are 775, 651, 645, 844
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(775, 651) = 16275
GCD(775, 651) = ( 775 x 651 ) / 16275
= 775 / 651
= 775
Step2:
LCM(31, 645) = 19995
GCD(31, 645) = ( 31 x 645 ) / 19995
= 31 / 645
= 31
Step3:
LCM(1, 844) = 844
GCD(1, 844) = ( 1 x 844 ) / 844
= 1 / 844
= 1
So, Greatest Common Divisor of 775, 651, 645, 844 is 1
