Given numbers are 121, 218, 263, 628
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(121, 218) = 26378
GCD(121, 218) = ( 121 x 218 ) / 26378
= 121 / 218
= 121
Step2:
LCM(1, 263) = 263
GCD(1, 263) = ( 1 x 263 ) / 263
= 1 / 263
= 1
Step3:
LCM(1, 628) = 628
GCD(1, 628) = ( 1 x 628 ) / 628
= 1 / 628
= 1
So, Greatest Common Divisor of 121, 218, 263, 628 is 1
