Given numbers are 400, 981, 91, 830
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 981) = 392400
GCD(400, 981) = ( 400 x 981 ) / 392400
= 400 / 981
= 400
Step2:
LCM(1, 91) = 91
GCD(1, 91) = ( 1 x 91 ) / 91
= 1 / 91
= 1
Step3:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
So, Greatest Common Divisor of 400, 981, 91, 830 is 1
