Given numbers are 643, 521, 603, 740
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 521) = 335003
GCD(643, 521) = ( 643 x 521 ) / 335003
= 643 / 521
= 643
Step2:
LCM(1, 603) = 603
GCD(1, 603) = ( 1 x 603 ) / 603
= 1 / 603
= 1
Step3:
LCM(1, 740) = 740
GCD(1, 740) = ( 1 x 740 ) / 740
= 1 / 740
= 1
So, Greatest Common Divisor of 643, 521, 603, 740 is 1
