Given numbers are 476, 550, 286, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(476, 550) = 130900
GCD(476, 550) = ( 476 x 550 ) / 130900
= 476 / 550
= 476
Step2:
LCM(2, 286) = 286
GCD(2, 286) = ( 2 x 286 ) / 286
= 2 / 286
= 2
Step3:
LCM(2, 639) = 1278
GCD(2, 639) = ( 2 x 639 ) / 1278
= 2 / 639
= 2
So, Greatest Common Divisor of 476, 550, 286, 639 is 1
