Given numbers are 162, 660, 409, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(162, 660) = 17820
GCD(162, 660) = ( 162 x 660 ) / 17820
= 162 / 660
= 162
Step2:
LCM(6, 409) = 2454
GCD(6, 409) = ( 6 x 409 ) / 2454
= 6 / 409
= 6
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 162, 660, 409, 257 is 1
