Given numbers are 657, 261, 435, 838
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 261) = 19053
GCD(657, 261) = ( 657 x 261 ) / 19053
= 657 / 261
= 657
Step2:
LCM(9, 435) = 1305
GCD(9, 435) = ( 9 x 435 ) / 1305
= 9 / 435
= 9
Step3:
LCM(3, 838) = 2514
GCD(3, 838) = ( 3 x 838 ) / 2514
= 3 / 838
= 3
So, Greatest Common Divisor of 657, 261, 435, 838 is 1
