Steps to Calculate GCD of 521, 362, 781, 189 using LCM Formula
Given numbers are 521, 362, 781, 189
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(521, 362) = 188602
GCD(521, 362) = ( 521 x 362 ) / 188602
= 521 / 362
= 521
Step2:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
Step3:
LCM(1, 189) = 189
GCD(1, 189) = ( 1 x 189 ) / 189
= 1 / 189
= 1
So, Greatest Common Divisor of 521, 362, 781, 189 is 1
