Given numbers are 340, 638, 803, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(340, 638) = 108460
GCD(340, 638) = ( 340 x 638 ) / 108460
= 340 / 638
= 340
Step2:
LCM(2, 803) = 1606
GCD(2, 803) = ( 2 x 803 ) / 1606
= 2 / 803
= 2
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 340, 638, 803, 921 is 1
