Given numbers are 554, 143, 253, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(554, 143) = 79222
GCD(554, 143) = ( 554 x 143 ) / 79222
= 554 / 143
= 554
Step2:
LCM(1, 253) = 253
GCD(1, 253) = ( 1 x 253 ) / 253
= 1 / 253
= 1
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 554, 143, 253, 639 is 1
