Steps to Calculate GCD of 85, 49, 87, 47 using LCM Formula
Given numbers are 85, 49, 87, 47
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(85, 49) = 4165
GCD(85, 49) = ( 85 x 49 ) / 4165
= 85 / 49
= 85
Step2:
LCM(1, 87) = 87
GCD(1, 87) = ( 1 x 87 ) / 87
= 1 / 87
= 1
Step3:
LCM(1, 47) = 47
GCD(1, 47) = ( 1 x 47 ) / 47
= 1 / 47
= 1
So, Greatest Common Divisor of 85, 49, 87, 47 is 1
