Given numbers are 921, 117, 202, 830
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 117) = 35919
GCD(921, 117) = ( 921 x 117 ) / 35919
= 921 / 117
= 921
Step2:
LCM(3, 202) = 606
GCD(3, 202) = ( 3 x 202 ) / 606
= 3 / 202
= 3
Step3:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
So, Greatest Common Divisor of 921, 117, 202, 830 is 1
