Given numbers are 380, 703, 138, 555
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(380, 703) = 14060
GCD(380, 703) = ( 380 x 703 ) / 14060
= 380 / 703
= 380
Step2:
LCM(19, 138) = 2622
GCD(19, 138) = ( 19 x 138 ) / 2622
= 19 / 138
= 19
Step3:
LCM(1, 555) = 555
GCD(1, 555) = ( 1 x 555 ) / 555
= 1 / 555
= 1
So, Greatest Common Divisor of 380, 703, 138, 555 is 1
