Given numbers are 285, 257, 526, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 257) = 73245
GCD(285, 257) = ( 285 x 257 ) / 73245
= 285 / 257
= 285
Step2:
LCM(1, 526) = 526
GCD(1, 526) = ( 1 x 526 ) / 526
= 1 / 526
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 285, 257, 526, 649 is 1
