Given numbers are 247, 884, 405, 705
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 884) = 16796
GCD(247, 884) = ( 247 x 884 ) / 16796
= 247 / 884
= 247
Step2:
LCM(13, 405) = 5265
GCD(13, 405) = ( 13 x 405 ) / 5265
= 13 / 405
= 13
Step3:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
So, Greatest Common Divisor of 247, 884, 405, 705 is 1
