Given numbers are 245, 715, 124, 862
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 715) = 35035
GCD(245, 715) = ( 245 x 715 ) / 35035
= 245 / 715
= 245
Step2:
LCM(5, 124) = 620
GCD(5, 124) = ( 5 x 124 ) / 620
= 5 / 124
= 5
Step3:
LCM(1, 862) = 862
GCD(1, 862) = ( 1 x 862 ) / 862
= 1 / 862
= 1
So, Greatest Common Divisor of 245, 715, 124, 862 is 1
