Given numbers are 400, 986, 785, 394
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 986) = 197200
GCD(400, 986) = ( 400 x 986 ) / 197200
= 400 / 986
= 400
Step2:
LCM(2, 785) = 1570
GCD(2, 785) = ( 2 x 785 ) / 1570
= 2 / 785
= 2
Step3:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
So, Greatest Common Divisor of 400, 986, 785, 394 is 1
