Given numbers are 820, 148, 255, 849
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 148) = 30340
GCD(820, 148) = ( 820 x 148 ) / 30340
= 820 / 148
= 820
Step2:
LCM(4, 255) = 1020
GCD(4, 255) = ( 4 x 255 ) / 1020
= 4 / 255
= 4
Step3:
LCM(1, 849) = 849
GCD(1, 849) = ( 1 x 849 ) / 849
= 1 / 849
= 1
So, Greatest Common Divisor of 820, 148, 255, 849 is 1
