Given numbers are 794, 638, 639, 253
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(794, 638) = 253286
GCD(794, 638) = ( 794 x 638 ) / 253286
= 794 / 638
= 794
Step2:
LCM(2, 639) = 1278
GCD(2, 639) = ( 2 x 639 ) / 1278
= 2 / 639
= 2
Step3:
LCM(1, 253) = 253
GCD(1, 253) = ( 1 x 253 ) / 253
= 1 / 253
= 1
So, Greatest Common Divisor of 794, 638, 639, 253 is 1
