Given numbers are 221, 147, 998, 262
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 147) = 32487
GCD(221, 147) = ( 221 x 147 ) / 32487
= 221 / 147
= 221
Step2:
LCM(1, 998) = 998
GCD(1, 998) = ( 1 x 998 ) / 998
= 1 / 998
= 1
Step3:
LCM(1, 262) = 262
GCD(1, 262) = ( 1 x 262 ) / 262
= 1 / 262
= 1
So, Greatest Common Divisor of 221, 147, 998, 262 is 1
