Prime factors of 615 are 3 x 5 x 41
Prime factors of 207 are 3 x 3 x 23
Prime factors of 820 are 2 x 2 x 5 x 41
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 744, 615, 207, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(744, 615) = 152520
GCD(744, 615) = ( 744 x 615 ) / 152520
= 744 / 615
= 744
Step2:
LCM(3, 207) = 207
GCD(3, 207) = ( 3 x 207 ) / 207
= 3 / 207
= 3
Step3:
LCM(3, 820) = 2460
GCD(3, 820) = ( 3 x 820 ) / 2460
= 3 / 820
= 3
So, Greatest Common Divisor of 744, 615, 207, 820 is 1
