Given numbers are 665, 860, 357, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 860) = 114380
GCD(665, 860) = ( 665 x 860 ) / 114380
= 665 / 860
= 665
Step2:
LCM(5, 357) = 1785
GCD(5, 357) = ( 5 x 357 ) / 1785
= 5 / 357
= 5
Step3:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
So, Greatest Common Divisor of 665, 860, 357, 409 is 1
