GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 891) = 559548
GCD(628, 891) = ( 628 x 891 ) / 559548
= 628 / 891
= 628
Step2:
LCM(1, 899) = 899
GCD(1, 899) = ( 1 x 899 ) / 899
= 1 / 899
= 1
Step3:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
So, Greatest Common Divisor of 628, 891, 899, 545 is 1
