GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(513, 507) = 86697
GCD(513, 507) = ( 513 x 507 ) / 86697
= 513 / 507
= 513
Step2:
LCM(3, 543) = 543
GCD(3, 543) = ( 3 x 543 ) / 543
= 3 / 543
= 3
Step3:
LCM(3, 645) = 645
GCD(3, 645) = ( 3 x 645 ) / 645
= 3 / 645
= 3
So, Greatest Common Divisor of 513, 507, 543, 645 is 3
