GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(165, 351) = 19305
GCD(165, 351) = ( 165 x 351 ) / 19305
= 165 / 351
= 165
Step2:
LCM(3, 639) = 639
GCD(3, 639) = ( 3 x 639 ) / 639
= 3 / 639
= 3
Step3:
LCM(3, 524) = 1572
GCD(3, 524) = ( 3 x 524 ) / 1572
= 3 / 524
= 3
So, Greatest Common Divisor of 165, 351, 639, 524 is 1
