Steps to Calculate GCD of 842, 761, 771, 856 using LCM Formula
Given numbers are 842, 761, 771, 856
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 761) = 640762
GCD(842, 761) = ( 842 x 761 ) / 640762
= 842 / 761
= 842
Step2:
LCM(1, 771) = 771
GCD(1, 771) = ( 1 x 771 ) / 771
= 1 / 771
= 1
Step3:
LCM(1, 856) = 856
GCD(1, 856) = ( 1 x 856 ) / 856
= 1 / 856
= 1
So, Greatest Common Divisor of 842, 761, 771, 856 is 1
