Given numbers are 513, 649, 431, 693
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(513, 649) = 332937
GCD(513, 649) = ( 513 x 649 ) / 332937
= 513 / 649
= 513
Step2:
LCM(1, 431) = 431
GCD(1, 431) = ( 1 x 431 ) / 431
= 1 / 431
= 1
Step3:
LCM(1, 693) = 693
GCD(1, 693) = ( 1 x 693 ) / 693
= 1 / 693
= 1
So, Greatest Common Divisor of 513, 649, 431, 693 is 1
