Given numbers are 638, 660, 943, 262
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 660) = 19140
GCD(638, 660) = ( 638 x 660 ) / 19140
= 638 / 660
= 638
Step2:
LCM(22, 943) = 20746
GCD(22, 943) = ( 22 x 943 ) / 20746
= 22 / 943
= 22
Step3:
LCM(1, 262) = 262
GCD(1, 262) = ( 1 x 262 ) / 262
= 1 / 262
= 1
So, Greatest Common Divisor of 638, 660, 943, 262 is 1
