Given numbers are 663, 717, 526, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 717) = 158457
GCD(663, 717) = ( 663 x 717 ) / 158457
= 663 / 717
= 663
Step2:
LCM(3, 526) = 1578
GCD(3, 526) = ( 3 x 526 ) / 1578
= 3 / 526
= 3
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 663, 717, 526, 257 is 1
