Given numbers are 377, 398, 803, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(377, 398) = 150046
GCD(377, 398) = ( 377 x 398 ) / 150046
= 377 / 398
= 377
Step2:
LCM(1, 803) = 803
GCD(1, 803) = ( 1 x 803 ) / 803
= 1 / 803
= 1
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 377, 398, 803, 639 is 1
