Given numbers are 506, 262, 390, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(506, 262) = 66286
GCD(506, 262) = ( 506 x 262 ) / 66286
= 506 / 262
= 506
Step2:
LCM(2, 390) = 390
GCD(2, 390) = ( 2 x 390 ) / 390
= 2 / 390
= 2
Step3:
LCM(2, 257) = 514
GCD(2, 257) = ( 2 x 257 ) / 514
= 2 / 257
= 2
So, Greatest Common Divisor of 506, 262, 390, 257 is 1
