Given numbers are 386, 926, 931, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(386, 926) = 178718
GCD(386, 926) = ( 386 x 926 ) / 178718
= 386 / 926
= 386
Step2:
LCM(2, 931) = 1862
GCD(2, 931) = ( 2 x 931 ) / 1862
= 2 / 931
= 2
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 386, 926, 931, 639 is 1
