GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 278) = 178754
GCD(643, 278) = ( 643 x 278 ) / 178754
= 643 / 278
= 643
Step2:
LCM(1, 427) = 427
GCD(1, 427) = ( 1 x 427 ) / 427
= 1 / 427
= 1
Step3:
LCM(1, 199) = 199
GCD(1, 199) = ( 1 x 199 ) / 199
= 1 / 199
= 1
So, Greatest Common Divisor of 643, 278, 427, 199 is 1
