Given numbers are 291, 639, 844, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(291, 639) = 61983
GCD(291, 639) = ( 291 x 639 ) / 61983
= 291 / 639
= 291
Step2:
LCM(3, 844) = 2532
GCD(3, 844) = ( 3 x 844 ) / 2532
= 3 / 844
= 3
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 291, 639, 844, 398 is 1
