Given numbers are 645, 467, 434, 479
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 467) = 301215
GCD(645, 467) = ( 645 x 467 ) / 301215
= 645 / 467
= 645
Step2:
LCM(1, 434) = 434
GCD(1, 434) = ( 1 x 434 ) / 434
= 1 / 434
= 1
Step3:
LCM(1, 479) = 479
GCD(1, 479) = ( 1 x 479 ) / 479
= 1 / 479
= 1
So, Greatest Common Divisor of 645, 467, 434, 479 is 1
