Given numbers are 830, 202, 407, 938
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 202) = 83830
GCD(830, 202) = ( 830 x 202 ) / 83830
= 830 / 202
= 830
Step2:
LCM(2, 407) = 814
GCD(2, 407) = ( 2 x 407 ) / 814
= 2 / 407
= 2
Step3:
LCM(1, 938) = 938
GCD(1, 938) = ( 1 x 938 ) / 938
= 1 / 938
= 1
So, Greatest Common Divisor of 830, 202, 407, 938 is 1
