Given numbers are 642, 433, 754, 289
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 433) = 277986
GCD(642, 433) = ( 642 x 433 ) / 277986
= 642 / 433
= 642
Step2:
LCM(1, 754) = 754
GCD(1, 754) = ( 1 x 754 ) / 754
= 1 / 754
= 1
Step3:
LCM(1, 289) = 289
GCD(1, 289) = ( 1 x 289 ) / 289
= 1 / 289
= 1
So, Greatest Common Divisor of 642, 433, 754, 289 is 1
