Given numbers are 391, 749, 665, 273
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 749) = 292859
GCD(391, 749) = ( 391 x 749 ) / 292859
= 391 / 749
= 391
Step2:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
Step3:
LCM(1, 273) = 273
GCD(1, 273) = ( 1 x 273 ) / 273
= 1 / 273
= 1
So, Greatest Common Divisor of 391, 749, 665, 273 is 1
