Given numbers are 162, 436, 169, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(162, 436) = 35316
GCD(162, 436) = ( 162 x 436 ) / 35316
= 162 / 436
= 162
Step2:
LCM(2, 169) = 338
GCD(2, 169) = ( 2 x 169 ) / 338
= 2 / 169
= 2
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 162, 436, 169, 639 is 1
