Given numbers are 238, 826, 355, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(238, 826) = 14042
GCD(238, 826) = ( 238 x 826 ) / 14042
= 238 / 826
= 238
Step2:
LCM(14, 355) = 4970
GCD(14, 355) = ( 14 x 355 ) / 4970
= 14 / 355
= 14
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 238, 826, 355, 489 is 1
