Given numbers are 210, 390, 922, 100
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 390) = 2730
GCD(210, 390) = ( 210 x 390 ) / 2730
= 210 / 390
= 210
Step2:
LCM(30, 922) = 13830
GCD(30, 922) = ( 30 x 922 ) / 13830
= 30 / 922
= 30
Step3:
LCM(2, 100) = 100
GCD(2, 100) = ( 2 x 100 ) / 100
= 2 / 100
= 2
So, Greatest Common Divisor of 210, 390, 922, 100 is 2
