Given numbers are 249, 371, 428, 705
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 371) = 92379
GCD(249, 371) = ( 249 x 371 ) / 92379
= 249 / 371
= 249
Step2:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
Step3:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
So, Greatest Common Divisor of 249, 371, 428, 705 is 1
