Given numbers are 138, 632, 373, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 632) = 43608
GCD(138, 632) = ( 138 x 632 ) / 43608
= 138 / 632
= 138
Step2:
LCM(2, 373) = 746
GCD(2, 373) = ( 2 x 373 ) / 746
= 2 / 373
= 2
Step3:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
So, Greatest Common Divisor of 138, 632, 373, 445 is 1
