Given numbers are 953, 421, 946, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(953, 421) = 401213
GCD(953, 421) = ( 953 x 421 ) / 401213
= 953 / 421
= 953
Step2:
LCM(1, 946) = 946
GCD(1, 946) = ( 1 x 946 ) / 946
= 1 / 946
= 1
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 953, 421, 946, 645 is 1
