Given numbers are 391, 292, 550, 853
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 292) = 114172
GCD(391, 292) = ( 391 x 292 ) / 114172
= 391 / 292
= 391
Step2:
LCM(1, 550) = 550
GCD(1, 550) = ( 1 x 550 ) / 550
= 1 / 550
= 1
Step3:
LCM(1, 853) = 853
GCD(1, 853) = ( 1 x 853 ) / 853
= 1 / 853
= 1
So, Greatest Common Divisor of 391, 292, 550, 853 is 1
