Steps to Calculate GCD of 207, 971, 272, 781 using LCM Formula
Given numbers are 207, 971, 272, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(207, 971) = 200997
GCD(207, 971) = ( 207 x 971 ) / 200997
= 207 / 971
= 207
Step2:
LCM(1, 272) = 272
GCD(1, 272) = ( 1 x 272 ) / 272
= 1 / 272
= 1
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 207, 971, 272, 781 is 1
