Given numbers are 253, 462, 284, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(253, 462) = 10626
GCD(253, 462) = ( 253 x 462 ) / 10626
= 253 / 462
= 253
Step2:
LCM(11, 284) = 3124
GCD(11, 284) = ( 11 x 284 ) / 3124
= 11 / 284
= 11
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 253, 462, 284, 257 is 1
