Steps to Calculate GCD of 215, 781, 159, 755 using LCM Formula
Given numbers are 215, 781, 159, 755
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 781) = 167915
GCD(215, 781) = ( 215 x 781 ) / 167915
= 215 / 781
= 215
Step2:
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
= 1 / 159
= 1
Step3:
LCM(1, 755) = 755
GCD(1, 755) = ( 1 x 755 ) / 755
= 1 / 755
= 1
So, Greatest Common Divisor of 215, 781, 159, 755 is 1
